New Ti Alloy(10 posts)

Today, I was reading a newspaper and found out an article about new Ti alloy called Ti-9. Ti-9 was developed by Kobe Steel Co. in Japan a while ago, but it has been used only for a metal plate for golf driver heads due to relatively high production cost. Now, Kobe Steel and an airplane manufacturer struck a deal in which Kobe Steel will provide the new alloy (tons of it, literally) to the manufacturer and drop the prodction cost significantly in exchange. A typical win-win situation. According to what I read, Ti-9 is lighter, stronger and can be made into thinner sheet metal than the conventional Ti alloy now we are so familiar with. That sounds terrific for the bicycle world as well. Who is going to use Ti-9 for building a bicycle first? And for how much? What could the ride quality be? I really wonder.

And we thought that the 2000 election was the defining low point for democracy. We thought that the Enron scandal was the pinical of corporate crime run amok. This has to trump them all! How many individuals are going to the federal penetentiary for this catastrophic abuse of natural resources?

I am just speculating...

the proporties that make a good driver in golf are light weight and the trampoline effect of the club face. Thus the metal used in the face of a club needs to be light and strong, but also have alot of energy or life.

I would think those charateristics would be perfect for use in a bike frame. Thinner tubes, with more strengh and energy in the frame. Good stuff.

The question would be, would the energy return from a thinner stronger Ti make for positive ride qualities?

Clubs are mainly made out of steel, steel bike frames rock.
If you need lighter and more powerful club you get Ti, Ti bikes rock hard.
If you need more power yet...?

I just can't help but think this new Ti would be amazing, if it were not wasted on golf clubs and planes.
I even saw TI knives for sales at Walgreens (nm)ColnagoFE

There are several grades of Ti that have higher strength characteristics then the common 3/2.5 and 6/4 grades used in bicycles. The golf club industry has been experimenting with these alloys for a few years now mostly for use on the face of super oversize drivers. Since these alloys are stronger, they can be made thinner without the risk of caving in. The thin face deflects at impact thus providing the desired "trampoline effect" (increasing the coefficient of restitution).

I'm not sure how malleable these new alloys are but assuming they are workable into a tubing shape, they could allow frame manufactures to push the envelope further in terms of large diameter thin wall lightweight frames.

Isn't technology grand!

what about welding? nmDougSloan

Ti-9 = Metax?Kerry

Metax is MAVIC's "proprietary" 6XXX alloy they use in the Open Pro rim. It could be a conventional alloy, but they're not telling. It could be that Ti-9 is just another conventional Ti alloy - there's no reference I could find with a Google search, and they usually turn up metallurgy information. Al and vanadium are the normal Ti alloying elements. Beware the hype.

Where did you read that newspaper? In Japan?
If so, can the Japanese news be trusted? Isnt it possible that this so called Ti-9 is just a myth?
