Titanium screws used bike

Titanium gives the impression that "light and hard." Keen lightweight riders tend to have replaced all the screws of titanium alloy plate alloy was satisfied. Titanium give some people the wrong impression, expensive and rare, in fact, titanium is one of the more abundant on earth burial abundant element.
Only because refining alloy production cost is very high, the price was expensive.
Titanium light weight, high strength, and high corrosion resistance of materials, usually used in a special environment.
After the addition of aluminum, vanadium (Li.V) in pure titanium, the alloy strength improved significantly.

Titanium mechanical properties:
Alloy Name Tensile strength (MPa) Endurance (Mpa) Elongation (%) E (GPa)
6Al-4V Ti (TC4) 980 920 14 110

Titanium products advantages:
Light weight, far more than the strength of steel, aluminum, lightweight and can produce high-intensity parts, such as screws class does not rust, titanium rod hardly etched in the general environment.
Riding feeling good, titanium is also used in the shock absorber spring. Now the frame made of titanium are suitable for long ride. Some riders love titanium frame that sense excellent ride. But individuals vary, and some people think that comparison chrome-molybdenum steel, chrome-molybdenum steel frame shock absorption better than titanium frame, riding feeling is better (shape it and chromium molybdenum steel frame than titanium rod for sale frame and thin The stress of the tube to get the increase is also relevant). If processing technology has been further improved titanium tube, there may be riding the same sense and chromium molybdenum steel.
