Titanium alloy bicycle racks are mainly produced in a customized manner. Due to the high strength of titanium alloys, it is difficult to form, and the processing of elbows is more difficult. The general elbow forming is to add lead or quartz sand to the inner hole, and heat it to about 400 degrees Bending and heating temperature control of the material are more important factors in the formation of the bicycle frame. The welding process determines the rigidity and strength of the entire frame. Because the value of the titanium alloy material is high, it is generally processed by hand and the output is relatively low, but Quality can be guaranteed.
