Product characteristics: With mechanical properties and corrosion resistance, and has a certain memory function, can restore the memory shape at the phase change temperature Its expansion rate is more than 20%, the fatigue life is up to 1*10 ^ 7, the damping characteristics are 10 times higher than ordinary spring materials, to meet the application needs of various industrial and laboratory research, is a very excellent functional material 1. Overelasticity at room temperature: maintain the material's super rebound effect at room temperature, but the elasticity will become worse and even softer at low temperature 2. Low temperature overshoot: The material still maintains sufficient rebound effect in the sub-zero state, but it is not suitable for use in high temperature environment 3. Temperature controlled material: the material is very soft at room temperature, and when heated to a certain temperature, the material cost will become straight and hard, resulting in a certain rigidity 4. Power contraction: After access to a certain rated power direct current, the nickel-titanium alloy wire will instantly produce linear contraction, and restore the original length after power failure If you purchase multiple pieces of Ni-Ti wire of the same size at one time, we will send continuous wire with a total length equal to the length of the Ni-Ti wire you purchased
