- Titanium has been called the luxury metal of the future, one that sculptors, architects, scientists, designers and jewellery-makers have praised for its strength and beauty. In this programme, we follow a jewellery designer and a craftsman to see how this unique metal can be transformed into some truly memorable pieces.
If u came to see interesting engineering, aeronautics and space applications of titanium. You are gonna have a bad time
so fkn angry..... at least its not from 2019, then they would be telling you all about how gay titanium is and the trans have claimed it as their metal because it can be rainbow.

Thanks. Yous safed me time
Haha I was so disappointed. Glad I saw your comment so I didn’t watch the whole thing
Thanks bro, imma leave now 😂
My father did government testing back in the 70's or so regarding best materials for use in space. Titanium ended up being the best material for its weight, temperature and resistance. For awhile, back in the days, the US government used to trade uranium to Russia for titanium. We had all the uranium and they had all the titanium. Good times.
Introducing the metal that will make it possible for us to visit other stars in magnificent spaceships that are the pinnacle of human ingenuity... Now let us tell you about the jewelry we're making.
Thank you titanium, you helped my skull heal back into a semblance of its former shape :)
Titanium is a beautiful material, respresenting both quality and understatement.
It's not valuable because it looks good, but because it's actually useful. Plus I love the color and how it feels.
Once it becomes simple to produce,titanium will be everywhere.
very light on the science, very heavy on the hot air. That one guy trying to act like he knew what he was about around the shop was funny to watch though
I came for the science and engineering angle. I left because it's about being rich and artsy.

Right. What a let down with such a title. I'll go back to watching steel mills and lathes.
Search abomb79 he's good
Me too, I came here from an ore deposits video. lol
so this documentary has turned the metal of the gods into the metal of the snobs
+Catalan Totanian Yeah fuck them assholes
+Catalan Totanian I'm something of a knife snob, the only 5 knives I have with titanium handles were $200 at the cheapest end. More a trend in folding knife making than anything though. The pricing is pretty silly, though I appreciate it is slightly harder to work with. The titanium camping gear I have saves a lot of weight, but they definitely make you pay for it.
anyone else scroll down at the lyfestile plug?
Not for long. There are currently new processes for liberating and working titanium. Expect titanium goods to be as cheap as aluminium or steel goods in the next 30 years. The Krull process is on it's way out for liberating titanium from it's ore bearing rock for starters. The demand for this metal is dramatically increasing for the new private space programs underway from the likes of Space X and this is putting huge pressures on finding cheaper ways of liberating and working the metal.
Katatonic4U tungsten is used in welding with various electricity. Going threw it . titanium is good too
I agree with most of the people on here, I thought this was going be about engineering. I have over a half a million dollars of titanium in my body, kinda wanted to learn more about it.
The pretension is a thick as I expected.
I used to have very bad pain in my shoulder every day to the point I couldn't sleep, and then I discovered by accident wearing a titanium ring helped greatly with reducing inflammation. I now where a titanium bracelet and ring on my hand and only have one day a month where the pain is at the same level it was, but only for about 30 minutes. Amazing metal.
Propably most stupid comment on TH-cam. Your jewelry has nothing to do with your pain.
11:53 ... wait a minute. The bike you're showing is not exactly cheap or common. It's a piece of motorcycle jewellery. The British company BSA ruled the motorcycle world in the 1950s, and they made a few 'all Titanium' BSA race bikes, which had both the frame and much of the engine made of Ti. It stands over 50 years later as a cautionary tale about what happens when executive types over-ride engineering types, because the board of directors wanted it but the race department didn't. It was an expensive catastrophe. They pretty much copied the parts they already made, but in Ti. Ti has different mechanical properties. Yes, it is very strong, but it is also brittle and prone to cracking, and repairing a crack (like for example welding it) in the field, is pretty much impossible. And two steel gears will work together, but one steel gear and a Ti gear, the titanium one will chew the steel one to bits, it's so much harder than normal mechanical steel... Ti is used today for connecting rods, rod bolts, and sometimes valves. It's not used much for anything else... It is not (in most ways) a good material to use for a motorbike frame. Like carbon fibre, it has been tried, and like carbon, it does have certain advantages, but it's a whole different proposition to work with...
Interesting post. I learned more from your post than watching this horrid vid.
@schmingus lingus - LOL - Thank you.

Which is why every application is assessed for the properties of the material.
Thanks to technology, aluminum-nickel alloys, like Inconel, Stelltite, Waspalloy, etc provide many identical properties, even some greater, like heat resistance. Google "Bell X-15" airplane. What they didn't say is that there are about 7 different Ti extraction process. The "bomb" it's placed in MUST be oxygen free & after a few days, it basically builds up on the wall of the Autoclave (ie "bomb") & must be chiseled off the "bomb" wall & then further processed (once again, all in an O2 environment). Even went welding, "TIG" - inhert gas welding, like argon MUST be used or the slightest bit of O2 contamination when hot will embrittle the weld/metal. Sad, because its grey finish, which changes colors when polished & exposed to different degrees of light, makes it unusual (in addition to its strength & heat resistance). It's perfect for joint (knee, hip, jaw..) as Ti is "micro-porous", magnified its like bone! Bone grows into the Ti making it like 1 natural piece & perfect medical repair
Makes me wonder what a gold-titanium alloy would be like.
I was looking for the song "Titanium" by "Metal of the Gods"
Anyone know where I can find it?
I've used Titanium on occasion so I know how expensive it can be. It is one of the few metals that the stockists will rarely quote a fixed price on. The reason being that they go off Titanium market prices on a daily basis...or so they would have me believe. So what you pay over the counter depends on the market price on the day you buy,much as happens with gold and silver.I also notice here that amongst the trendies,Titanium has attained a snob status which as an engineer I can only view with a certain amount of disdain. Other than its weight, in a highly polished state the only noticeable difference between Titanium and humble stainless steel lies in the over inflated prices they can dream up.
You can only tell the difference by holding them next to each other.
Stainless steel is brighter with a slightly blue nuance, while Titanium has a green hue.
did someone pay a Forbes magazine editor to say "titanium" 500 times?
Tan Tan yes. This is called a industry advertisement and supports all titanium jewelry in general and all high end designer jewelry in particular. Good observation Tan Tan-
Yes, I got in touch with TItanium about three yeas ago. I ues it to decorate my motorcycles , OMG!!!!!!!!!! SO COOL!
19:56 "titanium has strength, FLEXIBILITY, and versatility which is a rare material" Ignorant fashion guru you are making a fool out of yourself. Titanium in its pure form is extremely hard and brittle. Not flexible and versatile. And its not even rare. Its the 9th most abundant on the earth's crust!
Iron and aluminium and nickel are superior metals.
@@mattbanks3517 You mean iron aluminide and nickel aluminide.

Strong as Titanium, Cheap as Dirt: New Steel Alloy Shines
The strength of steel is proverbial, but that doesn't mean it can't be improved. It's heavy, after all, and there are stronger metals out there.
But researchers in South Korea have created an alloy that's as strong as titanium, lighter than ordinary steel, and cheap to boot.
The new alloy, described in the journal Nature, is created by alloying the steel with aluminum - this lightens the steel, but also makes it weak.
To counter that weakness, the team added a dash of manganese and a sprinkle of nickel, while modifying the way the metal crystals form at the nanometer scale.
This new alloy has no flashy name just yet but is referred to as High Specific Strength Steel. It has an even better strength-to-weight ratio than the far more expensive titanium.
This may bring steel back to industries where light, strong materials have become key, in particular the manufacturing of cars and planes. There's already interest in getting HSSS to the production line, so you may expect to see it (or ride in it) within the next few years.
A dash is generally equivalent to a little more than 1/16th of a teaspoon (of manganese powder or 4 or 5 drops of a liquid (molten manganese).
A springle adds about 300 mg of sodium (300 mg of nickel.
In a microfilm archived engineering textbook, one ounce of boron intensifies and doubles the alloying effects of any alloying ingredients added to steel to the point that one can reduce it to one half for every ounce of boron added to steel. There are 12 ounces in a single pound or 26.4 ounces in a single kilogram.
The rule is the boron to carbon ratio ranges from 50% of carbon to 100% of carbon. For example
if carbon steel contains 2% carbon then the boron content should be 1%. 1% carbon then the boron should be .50%.
Or one can maintain the original amount of required alloying ingredient without reducing it while adding one ounce of boron at a time to double it's alloying effect until the boron is 50% to 100% to that of the carbon content of the steel or iron.
Rate & Review. Adding a very small amount of an ingredient to a mixture, such as a "dash" of pepper, a "sprinkle" of salt, or a "few drops" of a liquid. A dash is generally equivalent to a little more than 1/16th of a teaspoon or 4 or 5 drops of a liquid.
How many milligrams is a sprinkle of salt?
To give you some perspective, one teaspoon of salt contains just over 2,300 mg of sodium! Even adding a pinch of salt, roughly 1/8 teaspoon, to a dish adds about 300 mg of sodium. What foods are high in sodium? Too much sodium increases a person's risk for high blood pressure.Jul 9, 2015

Great video thanks for taking the time to UpLoad it for the World to see.

Thanks for the update and beautiful technical avices break it starts over
I dont know about using titanium for art , but the frames of my glasses is made of it. They are strong as hell , light and they do look nice. At least that is what my girlfriend says.
tight anium - the metal for really tense applications used in a hole new way
11:22 More important than its conductivity is that gold is an excellent contact material because of it's non reactivity with mostly anything, and still being amongst the top three metals.
1.Silver
2.Copper
3.Gold
4.Aluminium
en.wikipedia.org/wiki/Electrical_resistivity_and_conductivity#Resistivity_and_conductivity_of_various_materials
Btw, gold has got many practical attributes; heat/light/radio reflection (IR-protection, Telescope mirrors), non reactivity, medicine in salt form, red glass, sepia photography, ice free windows, dentistry. Isotope for cancer treatment, as catalyst, Gold cyanide electrolyte. Boja!
could you imagine the power you could put through a forged titanium engine block?
Robert Anderson I was thinking that in a P-1 McLaren would be like a space ship on land-
Forged? That makes it weaker. They already make Alumimum-Titanium alloy billet (machine from a single piece) engine blocks. They handle upwards to 3000BHP.
i was thinking the same but for my motorcycle engine cranckshaft,rods,cylinders,valves and whatever else to get the most powerful motorcycle engine
yeah man n then sum, n.a let alone supachared
yeah, it wouldnt be pleasent. Titanium is extremely prone to galling so you would pick up flakes of it in the oilfilter within weeks, burns like magnesium, next to impossible to weld on and super brittle compared to all current alternatives.
Where is the scientific part of the documentary?
Flávio Viana Gomide are
Flávio Viana Gomide the title of the video has God in it. That should have told u right away that it's not a scientific video. They may have just called it titanium the voodoo metal, same difference.
lol, well played.
JusAnotherUTuber you do know that most scientific discoveries were founded by people of God, right?
+Brandon Leo Err... I think you might be wrong there. Scientific discoverers were all god-believers? Doubt it! And I hope never to hear from a scientist that he/she "founded" something - that would make a mockery of their work.
If i had to i'd rather use Titanium for an engineering project rather than wasting it on a piece of shit sheet metal sculpture.

Gold is the most exceptional metal, but that is mostly used for trivial jewellery.
You will be pleased to hear though, that the exhaust, many fasteners and a number of parts on my car are made from Ti.
+turboslag Wow! congratulations! Arrogant ass
+turboslag Gold is not exceptional, it's useless. Its' only value is its' rarity.
Jack Walters
Not exactly useless!! Electronics would be in a difficult place without it!!
There was in fact one true artist that mastered this miraculous material. And the art piece he crafted is as beautiful today as it was over 60 years ago when the greatest aeronautical engineer of all time brought us the strikingly beautiful and equally as functional, never surpassed, SR-71. The man, the visionary, THEE Artist, Mr. Kelly Johnson. Put that in your hash pipes and smoke it. He would a good laugh listening to these pompous assed, self described, artists. Rest in peace oh great one.
60's style ... 90's artists ... and it still matches the modern movie industry ... nothing but a remakes
they miss the point. It should be about enginering, not about some "artist" waisting it..
Agreed.. For buildings etc, Aluminium would work just as well. It's lighter, and much cheaper. Keep the titanium for where it's needed.
Agreed as well but if you want practicality don't watch TheLuxuryChannel. Luxury is not about practicality.
Totally agree, but titanium is really expensive to weld it, so engineering wise it may be extremely useful, but its just too expensive in some cases
Nedeljko Mrda Dint you mean waste? Waisting like a belt?
I have titanium cups, thermos, plates, bowls, pots and cutlery. It never rusts, is always easy to clean and weighs very little. Yes, Titanium is cool. ALso have a titanium walking stick and watch. Oh, and titanium toothpick, lol.
Titanium is also used for the buckles on marine safety helmets. Two main reasons (1) It never rusts. (2) It is lighter than stainless steel.
Titanium is also amazingly bullet resistant
1.4k ppl who disliked are ppl who were forced to watch this for welding class
The bike at 12:00 is not the first with a Ti frame. BSA made a scrambler (Motocross) bike with a Ti frame in the 60's. Ok, it was a works machine, not available to the public, but it was the first as far as I know. They had major issues with it though, so it wasn't around long.
1:30 Erm, no.. There are more than like 50 elemental metals that are more expensive than Ti..
i manufacture titanium, what we make is SO FLAMMABLE!
My left arm was crushed by a psycho with a pipe when I was a young boy in the 1970's. Though it was physically destroyed more than most, I have complete use of it to this day, because my parent's spent over 60 thousand dollars way back then and had my bones replaced with Titanium and I have never had a problem with it yet and even in a short sleeve shirt you cannot tell save for the almost now invisible scars !!! Furthermore, I have absolutely destroyed other men in actual fights where they attacked with hammers and never broke a sweat.
So you are a full grown man with a little boy arm?
They didn’t notice the brain damage.
Heres a question would a piece of pure Ti that is about 10lbs be worth anything. I acquired it while working at t foundry some 45 years ago.
And not one mention of the actual products most impacted by titanium; the hiking/outdoor market.
Mr. Tangent how about the fact that it's what replaced lead in paint? I think that beats out your little hiking/outdoor market. This documentary did not do justice for Titanium.
I always had a titanium watch and wedding ring for the weight. The lighter weight helped me maintain better fine motor skills in my hands for the work I did.
Guillaume Kroll, alias William Kroll was a Luxemburger and he invented the "Kroll process" to obtain Titanium. He invented the process in Luxembourg, area of Belair....
Awesome.. I love Titanium
Hello, I have my own titanium production line, which can cut and polish. Can I help you produce some order which maybe can help you save some time.
I know this may sound like an odd question but what does titanium smell like when it's being heated up towards its melting point at 3034 degrees Fahrenheit?
looking at the Guggenheim in Bilboa, then looking at the concrete monstrosity that is the Hepworth Gallery in Wakefield makes me dazzled with disbelief, to me the hepworth looks like it was designed by the same guy that designed Britains beach defences in 1940
these are literally the funniest comments on youtube
The first Artist used a industrial metal break on a tiny piece of titanium. You could bend it on a vise with your hand!
He seems very unfamiliar with his equipment also. Probably the guy that walks in with a vauge sketch and tells a room full of craftsman to make his vision a reality. Artists.....
Fast forward two years to 2015... I decided to invest in this expensive wonder metal. How? I spent an amazing amount on a watch that was made from Titanium, and am still wearing it now in 2016. So what makes it special? It's light, it looks nice, it's stronger than steel, and it tells the time... and only cost £40. Titanium may be wonderful, but it's just another metal to me... (Subnautica fans might disagree!)
The shots of that shilling dude "working" with a ridiculous suit and hat on are priceless
Titanium is a superior metal for race bike frames.
I enjoy riding one.Won‘t need another one this life,
best road performance ever experienced 🤙
Man, that titanium scooter looks boss.
I had a good friend (r.i.p.) who was machinist employed at Skunkworks many years ago. The security there - at the time at least - must not have been that great, because he machined a titanium bolt into a pot pipe then took it home. smh
LMFAO!!!!!!!!

There are videos out there documenting the construction of he SR-71 which are astounding!!

Can someone please tell me the name of that Dave-Clark-like-band that played out the credits.
It's a funny material, so soft that its easily marked, but it's difficult to cut, tap or drill, as the tools wore out very quickly... I used to hate working with the stuff when I was an engineer!
I just can't take the effeminate snobbery. Thumbs-down @2:43...
dave the man , the artIs the hat
I like how you gloss over the fact that militaries are the main consumers of titanium, and have actually driven innovation in how to work the metal. You don't make an entire submarine hull out of titanium and not learn things. In fact, the SR-71 Blackbird is the highest expression to date of the possibilities of Titanium as art. It had to be, as the body would melt if using steel or aluminum at Mach 3/ 2500 mph/3700 kph. 60 years later, it's still the fastest plane ever flown, by a wide margin, a testament to the design and build materials used. Art/architecture are a miniscule percentage of titanium production and use, even here 6 years in the future.
Thank you for spreading the truth 🙏 I actually believed this video because i thought it was a legit documentary 😂 should have done more research
Even though Titanium transfers heat beautifully, it diffuses it badly. Which makes it a terrible metal for cooking pots and pans, since it would burn the food that sits above the spot where the heat is coming from.
But since it transfers heat so well, its perfect for just boiling water in a small cup. Like the titanium cup backpackers buy from a company named - Snow Peak.
This is not a commercial, I promise I don't work for them!
a documentary about the eternal hunger of the rich and fickle for something new.
they really do live in a bubble...
this is like watching a movie made up of commercials.
U probably walk on it everyday, it's found in sand. Its the MOST ABUNDANT metal in the world (some say AL is, but either way Ti & AL are VERY ABUNDANT). It's the processing that makes Ti's price so high... Many stages, MOST must be done in an "inhert" - non O2 environment & basically, many steps require human labor. The price has drastically come down though over the years thanks to increased use & production, but it's still one of, if not the most costly "non-precious" metal-alloy (notice I said alloy... No one uses "pure 100% Ti, or Au, etc. There's always a % or 2 of a few things added to "bring out its best qualities").

They adopt condescending tones and associate them with education/knowledge thereby thwarting anybody who isn't familiar with those behaviors from pursuing higher education. They aren't citizens.

He's also wrong about the coloring process being a one-shot risk. It only shimmers different colors because of different oxide thickness and refraction. If you get the color wrong, wash in hydrofluoric acid and try again.
Boy, I gotta say, the preceding commentary is spot on. I will also mention that if you think titanium is 'the metal of the gods' .. then you ought to look into element 140 .. yeah thats right, element 1 4 0 .. what's that u say ? There is no element on the periodic table ? You're right. The establishments periodic table is not the publics periodic table. This element is the 'alienalloy unobtanium of the gods' .. in every conceivable way .. and then a shit load more. That is why it isn't reflected on ANY chart. Its capabilities are so astounding that the average human simply will not believe. It was not discovered by humans but was given to a very small select number of humans. It is synonymous to electrical power companies - fossil fuels - and central banking - they are all designed to bilk the populous for the benefit of a very very few. Welcome to 2018.
Most people would not buy this because they know it`s isn't precious or rare, only those with too much money will buy it to show they have something few others can afford.
As for making a motorbike out of it for two hundred grand that reaches 150 Mph, my old Honda CBR 1000 would do that and more in around fifteen seconds. Although I can appreciate the craftsmanship most of this stuff is for People who worship Money and live the high life in places like Monaco, LA & Dubai, real craftsmanship does not require a Cash Value to make it ART. This is just a reflection of how the World of Art needs to Big itself up to give it credibility and value it often does not deserve.
These guys are way out of date. I have a 1L titanium water bottle. No chemicals like plastic, won't dent like stainless or aluminum, and cost me about $150. Had it for 5 years now and use it every day. Only a few very minor dings in it. The corrosion resistance means it can be cleaned with bleach. Even the cap is titanium with machined threading.
Hell, back in 2008 in college I was using titanium cookware because it was durable, easy to clean, and affordable. Still have it and use it.
Have a titanium watch too. Solar powered and designed not to need service for 30 years. I got it specifically because it was lightweight and corrosion resistant.
I even have a titanium toolkit for working with high strength magnets and in high magnetic field environments. It was very affordable and never wears out.
As for their comments about gold, that's only because it is so rare. If Gold were more common people would use it for all sorts of stuff.
i have a few razors made of titanium and they're so nice.
The barrel of a custom made gun that I own is made from titanium it’s a leftover piece from a Roto gun amazing amazing amazing metal
What would it take ,financially to produce a 3d printed pedicab. Red would be nice
Wikipedia shows Titanium's Melting point 1668 °C, 3034 °F but THIS video at 7 min 10 sec into the play says the melting point as 1800 C which is WRONG by 132 C or 237.6 F more than the actual amount. Simple facts should be correct.
try making a titanium ring and when you cant get it off your finger see how you will cut it or will you cut your finger
At around 11:30 a guy says that gold is a really good conductor of electricity, it's not. Copper is much better, and silver is much better again. Gold's major attributes for use in electronics are that it won't react with anything naturally occurring in the environment making it able to protect say the underlying copper, and it is extremely ductile and barely work hardens making it great for the bonding wires within IC's. Here also the fact that gold doesn't much like to react means that little doping occurs where the gold bonds to the semiconductor.
Interesting documentary but as Flavio Viana Gomide says, where is the science part?
Beautiful scenic view of the ocean and they put some stupid ass triangles blocking the view.
as we stay tecnological and scientific here, is the use of "of the gods" a little bit "antinomique"? if I may say....
Who is allergic against metal could use titanium jewelry. I'm no goldsmith, so I'd made it on the lathe. And it's easy to polish.
I laughed at him holding the grinder.
The title should be "How to waste good material on human vanity".
Using a side grinder with no safety protection at all…no eye or ear protection…no gloves. Very foolish to be doing this kind of work and not taking any precautions to protect yourself.
I am a WIS and I don't like titanium watches.
It's great news that it will get cheaper and used where it's really needed.
I have Titanium in my jaw waiting for a crown. The cost is prohibitive now and dental insurance does not like paying what the industry demands unfortunately!
Why this video trends high on TH-cam is a mystery. Could be the title. One just has to read the comments to see it is click bait at its worst.
All said,over 800 thousand views,....don't think editing would had brought more,their point was made
It says nothing of making cutlery from it, with inlaid melted colors. Space travel is the best application by far.
well you could rather do some awesome engineering with the titanium they use... Also Titanium is everything but carbon footprint friendly cause it uses that much energy to gain.

I had a bicycle frame and many other bike parts made of titanium and also a watch made of it. Titanium is not that expensive as this documentary may make you think. It is a bit more expensive because it is not easy to weld or to form parts into shape because of its hardness. I'd paid 450 Euros for an 1,5 kilo frame. So one gram cost me around 45 cents. That's cheaper than silver. If there are idiots out there who pay 2000 bucks for 5 grams of titanium jewelry so go on waste your money for crap.
I was walking along when my glasses thin right side bar went 'ping' and broke in half spontaneously. titanium can undergo a sort of phase change . I used to know a Rolls Royce engineer who told me about the first titanium fan blades on the RB211 engine that used to spontaneously change their pitch (bend) and how they had to anneal them to stop it.
Titanium makes very good hygienic cutlery, Stuff the fashion.
