Now thousands of bike materials are very light, what advantages and disadvantages of this material?
Titanium alloy has the advantages of light, high strength and good toughness, but the price is too high and the process is complex and difficult to be popularized. The average person is not for a good thousands or tens of thousands of frame only. But the good toughness and strength of titanium alloy is a good choice for fancier.
Carbon fiber: light weight, strong strength, good toughness, but high price. Now, the tour de France and other races are usually made of carbon fiber. But now the production of carbon fiber is used as some brand-name small factory signs, do many inferior low carbon fiber frame will affect the general understanding of the carbon fiber, the real carbon fiber frame strength quality is great, the strength of carbon fiber is ten times Aluminum Alloy strength, but if the carbon fiber quality not to say, carbon fiber is to be produced in a clean room, if there is a small bubble will affect the whole frame strength, even life-threatening. Therefore, the high-grade carbon fiber frame is more expensive. The disadvantage of carbon fiber is its impact on the high pressure, low impact, such as taking a sharp screwdriver, a vertical puncture frame, no aluminum alloy and high carbon steel, strong tolerance. But this situation can not be considered, who does not torture his car ah. There is no problem with collisions and falls in general competitions.
Now the mainstream is aluminum alloy and carbon fiber and titanium alloy. Aluminum alloy has the advantages of light weight, high strength and low price, but its toughness is not good. In the downhill or high intensity competition, the toughness is not enough, and it is not safe and is not conducive to the challenge level.
