Ni Ti alloy is a kind of shape memory alloy. Shape memory alloy is a special alloy which can automatically restore its plastic deformation to its original shape at a certain temperature. Its expansion rate is more than 20%, its fatigue life is 7 times of 1 * 10, its damping property is 10 times higher than that of ordinary spring, its corrosion resistance is better than the best medical stainless steel at present, so it can meet the application requirements of various engineering and medicine, and it is a very excellent functional material.
In addition to its unique shape memory function, memory alloy also has excellent characteristics of wear resistance, corrosion resistance, high damping and super elasticity.
