Titanium bicycle parts application development

Titanium bicycle components are connected to the frame of the crank positioner, pedals, handlebars, etc., TI-3AL-2.5V titanium bike rack industry has developed rapidly, most of the components are made of Ti-6AI-4V, parts Most are machined out of titanium rods or titanium plates. Ti-6A1-4V components with the price are only TI-3AL-2.5V frame 1/3. Titanium suppliers are beginning to offer substandard parts to titanium parts manufacturers, most of which are virtually eliminated aeronautical materials. Compact, good stiffness and lightweight is the general requirements for driving specifications for bicycles. Titanium does not usually the best material. Wrought aluminum and cast aluminum are more popular. If the price of titanium matrix composite material is reduced, it may become the current Alternatives to the aluminum market. The material requirements of the frame are simply, but the driving characteristics are particularly critical, making the choice of materials complicated in some respects. Most transport vehicles, structural elements and internal facilities and operating elements are separated until recently, all bicycle frame requirements With structural integrity and suspension capabilities. No single titanium alloy is designed for bicycles at the moment, only some materials have been altered for bicycles, and most people consider the cost reduction, while the major problem with titanium parts is rigidity rather than cost. Ti-3Al-2..5V is the most commonly used bicycle titanium, although it is designed for aircraft hydraulic system, but due to formability, corrosion resistance. High fatigue strength-to-weight ratio and good elongation make it in line with the bicycle market performance standards, compared with other titanium alloys, Ti-3Al-2.5V biggest advantage is the yield strength and tube forming easy, the disadvantage is its price and mode The difference between the amount and density. It is difficult to extrude Ti-3Al-2.5V as the dominance of the frame material. Ti-6AI-4V also has some appeal, its modulus and strength are higher than the Ti-3Al-2.5V, but the processing of such a small diameter bike frame is tough. Ti a 15V-3Al a 6Cr-4Mo-4Zr also easy to shape, but its higher density. Lower modulus offset its strength in the increase.

If the titanium industry is interested in developing the titanium sporting goods industry, including bicycles and wheelchairs, it should not only to advertise the producers, but also promote the end users of the products. After the failure of the titanium frame in the 1970s, Ti-3A1-2.5V pipes, despite their improved performance, are susceptible to the low cost of commercially available titanium frame currently available on the market, plus There are titanium frames made by small companies that do not have the knowledge and resources they need to create successful titanium products that affect titanium's reputation in the bicycle industry and other consumer products.
