The Sexiest Metal

Science 535

jonerik writes "Denver's weekly Westword magazine has this article on titanium and the attempts to break it out of its traditional aerospace/defense industry niche, including its growing use in architecture, computers, jewelry, sports, knives, cars, medicine, and other areas. The upside: It's as strong as steel but weighs half as much, it doesn't rust, and it's fairly plentiful. The downside: It's expensive compared to steel and aluminum and its high melting point makes it difficult to work with under some conditions. Still, it's nice to see it being used in other applications." Heck, I know someone who used it as his wedding ring. Pretty cool, actually.

I HAD to get titanium frames on my glasses, because my sweat is so acidic. The other glasses I used to wear when I worked out had some type of metal that was pulverized after one year of sweat exposure. The titanium looks just like new, after almost two years. Did I mention they are light. :)

Flarners (458839) | more than 12 years ago | (#3325464)

Titanium may be as strong as steel, but it's far easier to bend when cut thin. Anybody who has one of the titanium PowerBooks will attest to the fact that if you try to pick them up from one end, the thing will bend disturbingly. This is why you won't see titanium in kitchen sinks, silverware or anywhere else where the metal needs to be thin, strong, and unflexible. The only thing it has going over steel in these cases is buzzword compliance and price (if it's more expensive, it must be better!)

Flarners (458839) | more than 12 years ago | (#3325589)

The newer TiBooks are reinforced in order to prevent this bending problem. The first few runs of them (including my own) flop around to a dangerous degree unless you make sure to pick them up with both hands. If a CD or DVD's in its drive, you can hear it getting scuffed up by the drive hardware when it bends! Apple's "designer" computers have a history of problems in the first run (heat fissures in the plastic moulding of the G4 cubes come to mind). Be glad you weren't an early adopter :)

Shinobi (19308) | more than 12 years ago | (#3325569)

Considering that titanium has been used in mountainbike frames for at least 8 years, and in quite a thin layer, especially compared to the steel/cro-mo frames, and have proven themselves to be just as durable, you are quite wrong. I used to compete in mountainbiking, and I had a titanium frame. Me and another biker smashed into a rock at about 45km/h, with our bikes hitting the rock instead of us hitting it, and his alu 8005 frame got warped, his upper tube bending, while my titanium frame barely got scratched.

The core of the structure of an F-14 is Ti, and many other modern jets, but the F-14 being one of the earliest. This box of titanium in the center of the plane is just about the only thing that will survive a catastrophic crash. It also does so with very little damage (relatively) to it. Which brings up the whole... why not make the plane out of the black box question... and the answer is economy... and I'm sure defense secrets... I'd love to hear about some more aerospace uses...

I also recommend metalsmiths.com. They do some great work and they do have titanium rings. We got an engagement ring and two wedding bands from them and they were very well done and reasonably priced. My wedding band was titanium with a stripe of gold and my wife's was platinum (and the engagement ring was platinum with an emerald).

The one caveat I would say is that they do sometimes take a while since it is a small operation, so if you are planning to meet a specific timeline order well in advance.

I'd be nervous to wear a Ti ring. It's not uncommon for people to badly jam a finger and have to visit an ER to have the ring cut off. My understanding is that this would be very hard to do if the ring is titanium.

4of12 (97621) | more than 12 years ago | (#3325501)

If you haven't been married for long you probably don't know that sometimes, when people gain weight, the rings start to become, uh, constrictive.

With a traditional soft gold alloy you can snip the tight ring with a pair of bolt cutters or even wire cutters for thinner gauge rings.

With titanium, I don't think you'd have such an easy time removing a stuck ring. A cutting torch is not going to leave much of a finger and using a diamond saw, too, could be real tricky with in vivo parts involved.

Watches are some of the most common consumer goods available in titanium. Citizen is the largest titanium watch maker in the world.

A concern with titanium watches is that, while they're light and strong, they also tend to scratch more easily than steel. This is a concern because in time a titanium watch will look more battered than a stainless steel one. Citizen actually claims to have a process to reduce titanium's "softness" (can't recall if it's an alloy or a special coating), thus reducing this problem.

I finally got a new Seiko watch about a year ago, a simple analog kinetic model with a titanium band. Previously I've worn a big heavy steel-bracelet model.

Price and 'sexiness' aside, there are some real advantages to titanium watch bands. All of the strength of a steel band, at a fraction of the weight. I've also noticed that this watch doesn't feel as cold in winter.

I find that Plastic bands do not last, leather bands get sweaty. IMHO, a metal band with a good fit (not too tight, not too loose) works best for me, and they last forever with only minor scratches.

One drawback -- the dull "grayish" hued TI shows scratches more than my old (shiny steel) band. I like the less flashy look (compared to steel) and the lower weight... I've had plastic "sports watches" that weigh more.

When I received my order of the engineer ring [ironring.ca] , one of the speakers mentioned that it's a very good idea to remove the ring while working with machinery, even moreso than with normal jewelry.

Ti is also what was used to cover the new guggenheim in bilbao, spain [guggenheim-bilbao.es] . Frank Gehry is a genius. originally he was going to use stainless steel. but it didn't catch the light quite the right way. then he saw titanium and was sold. he was worried that it costs 2x as much as stainless, but it was ok because it only had to be 1/2 as thick.

i love the total lack of right angles in that building. simply beautiful.

I've got Ti wedding rings (3, Informative)

Chairboy (88841) | more than 12 years ago | (#3325568)

My wife and I got married back on March 24, and we are both wearing excellent titanium rings from www.boonerings.com.

My ring is styled after Ed Harris's ring from The Abyss, and my wife has a pair of helix rings, one that holds a diamond through tension in a spectacular manner not possible with softer metals.

See: http://www.boonerings.com/large/helixxlite.htm

In regards to safety, Titanium rings can be easilly removed using cutting tools present in most ERs.

Titanium and Corrosion (2, Informative)

Veramocor (262800) | more than 12 years ago | (#3325573)

Titanium is actually a very reactive metal even more so than Iron.

Fe = -.440
Ti= -1.63

Titaniums corrosion resistance is actually confered to it by the formation of titanium dioxide scales, TiO2 (same stuff in toothpastes go ahead look), the layer slows down the diffusion of oxygen and other oxideizers to the surface of the metal. Much like Chromium does in stainless steel (Cr2O3).

Is Titanium then the best metal for all corrosive environments? Hell no! Its protection is based on the thermodynamic stability of its scales.

Put your nice shiny new Titanium in a highly oxidizing and basic environment (look up Pourbaix diagrams if you want more info). Kiss it goodbye. While plain carbon steel would have resisted it since its scales are stable in that environment and a lot cheaper to. Had you used titanium for your reactor thinking it was the best, you my friend would have been fired.

The moral of the story, there is no one good metal for all applications. You need to consider many factors not to least mention cost.

Why so expensive (2)

GreyPoopon (411036) | more than 12 years ago | (#3325577)

If Titanium is plentiful, then why is it so blasted expensive? It can't be solely because it's hard to work with, can it? Is it expensive because it's currently only used for "special" applications? If we start using it more, will the cost go down?

wedding ring (1)

numbuscus (466708) | more than 12 years ago | (#3325578)

I have a titanium wedding ring. I got it because, well, it's cool and because I thought it would last forever. While it still looks good after 8 months, but it did scratch after the first week when I scraped it across some stainless steel. The scratch may only be in the polish though. Anyway, if someone wants to know, it cost about $200. I probably got screwed - damn weddings.

Let's bomb Iraq (0)

Anonymous Coward | more than 12 years ago | (#3325579)

I say if Iraq insists on it's oil embargo until Israeli troops leave Palestinian territories, then we should insist on bombing Iraq daily until they lift the oil embargo....

I think we have the artillery to hold out longer than they can.

it _is_ abundant (2)

cats-paw (34890) | more than 12 years ago | (#3325585)

Check out :

Although abundance doesn't necessarily mean it's easy to get to, or does it ?

There was an article in WSJ a while back which basically said that if Ti could be more easily extracted, it would take over steel. Apparently it's hard to get the metal out purely.

Obviously that's not true for TiO2 which is used as white pigment in darn near everything.

Titanium might be smooth and maybe even a little sexy, but the sexiest, and most stimulating metal is definetely "Tonguesten"...

Ti rings = bad news if injured (2, Interesting)

GreenKiwi (221281) | more than 12 years ago | (#3325606)

Wearing a ti ring is bad if you ever get injured and your finger swells. Most ER's are not capable of cutting through ti and as a result, you could be in a lot of trouble if you ever need to have it taken off.

Ti and acidy skin (2)

shibut (208631) | more than 12 years ago | (#3325610)


Many in my family were "blessed" with acidy sweat/skin. This means that any watch we buy aside from all plastic or all titanium will have it's mechanism eroded in a matter of weeks or months (depending on person). One clockmaker even asked if we dipped a 6 month old designer watch into the ocean for a day or 2... Anyway, with Titanium watches my brother has had the same (very expensive) watch for 3 years now. Since Plastic only goes so far, I bought Ti this year too (although w/ leather strap, but even the strap clasp is Ti). It's light and reliable - what more could we ask for?

ice screws! (2)

red_crayon (202742) | more than 12 years ago | (#3325612)

Various companies have been making Titanium ice screws for about 11 years now.

Lighter than Cr/Mo and rustproof, take more wear and tear then Al, and stronger, all things equal, than either one.

See for example. [ushba.com]

TRUTH :Titanium popular only because of discovery (1, Interesting)

Anonymous Coward | more than 12 years ago | (#3325624)

TRUTH :Titanium popular only because of discovery in 1998 on how to CHEAPLY make titanium.

Basically titanium dioxide (a common white powder used in paint and found all over this planet) was found in an amazing discovery to be able to be turned into pure titanium by dipping it in a hot salt and using electricity.

The titanium dioxide is shaped into a cathode in a fused salt cell and under an applied current, the oxygen leaves the oxide as oxygen ions, diffuses to the anode, where it is discharged. The titanium metal is simply left behind and at no stage in the process is the titanium in the liquid or ionised state. This is the major difference with the previous processes. Furthermore, as the titanium is not deposited from the salt, it is relatively inert. Another very surprising observation was that although titanium dioxide is an insulator, it acts as an efficient cathode. The reason for this is that as soon as a minute amount of oxygen is removed, the material becomes an electronic conductor that allows the electrochemical processes to take place. The overall process is that an insulating oxide is made the cathode in an electrochemical cell and the oxygen is extracted to leave pure titanium.

Its a miraculous discovery and though now titanium is dirt cheap... it is still unworkable into finished products. This makes it expensive because machining it is difficult.

It used to be that the material was expensive.

Apple rushed into the fray first with its use of titanium on its flagship computer products.

I wish people would stop acting like titanium is sexy and hot merely because of a fashion fad... its current popularity is soley based on an amazing discovery.

Makes great wedding rings... (0)

Spazholio (314843) | more than 12 years ago | (#3325630)

I had my wedding ring made out of titanium and gold. The gold is encased in the titanium, visible as a center ring sandwiched between the titanium. That ring has gotten more abused than any other ring I've had, and it's held up remarkably well. The occasional cleaning makes it look almost good as new.

You'll get my titanium spork... (2)

Ah, the titanium spork - a glimpse of the sacred within the profane.

Seriously, i trust the spork - I don't trust many of the titanium bike builders out there - do it right (Tom Kellogg) and you have a dream to ride. Do it wrong, and you've got something that will leave you cursing technology and send you right back to your trusty CroMo or Aluminum steed. And it's very very easy to do it wrong.

Makes great armour for Battlebots (1)

displacer (136053) | more than 12 years ago | (#3325649)

Nice thing about titanium is that it is very saw resistant, which makes it good for bottom armour on Battlebots (like mine). It also makes for good TV because when it is struck hard enough, or hit with a saw it makes nice big, bright white sparks. When you see those sparks on Battlebots, it's not special effects, it's Titanium!!
