Shape Memory Alloy Wire
Main uses: fishing line,super elastic memory alloy mobile phone antennas,optical glasses frames, Bluetooth headsets, medical.
Memory titanium alloy wire nickel alloy:
Features: good elasticity, high strength, no blisters and cracks on the surface, good stability for computer coils, and changes with the use. Nitinol is a shape memory alloy. Shape memory alloy is a special alloy that 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 1 * 10 to the 7th power, its damping characteristics are 10 times higher than ordinary springs, its corrosion resistance is better than the best medical stainless steel at present, so it can meet all kinds of engineering and Medical application needs are a very good functional material.
In addition to its unique shape memory function, memory alloys also have excellent characteristics such as wear resistance, corrosion resistance, high damping and super elasticity.
