Aluminum seamless pipe for bicycle and motorcycle frame
2023-07-06 11:33:25

Aluminum bicycle frames, mainly apply by 6061 F, some high-class bicycle using 7050, 7055, 7003, 7075 etc. As the aluminum alloy has advantage of light weight and corrosion resistance, anti-oxidation etc. Aluminum seamless pipe for bicycle and motorcycle frame are more widely used in the bick rack. The self developed 7XN5 new alloy pipe, can be used for bicycle main frame, making anti-bending fatigue performance from the traditional 60,000 to 120,000 times.

Aluminum alloy seamless pipe is sued in frame structure as hand parts, brake pads, brake plate etc, which ever automotive it is. Weighted sports racing vehicle requires, not only light weighted function and handing stability, but also on appearance to attract the eyes. Therefore, the wheel and controlling bottom beam, control pedal, etc, have all been made of the high strength and processed aluminum alloy.
