| The characteristic of titanium spring : resist rust ,resist high temperature, high strength ,high flexibility , none of magnetism ,be sensitive to reflection .the use of titanium spring : aviation 、military、ship、motor、bicycle、motorcycle、petroleum、 chemical industry 、electron mechanism、hardware and so on . Especially FTB 29 which is titanium alloy material for spring. It is titanium material of high intensity, high elasticity, and high performance of figuring. |
