Nitinol Wire Nickel Titanium Alloy Wire
Product introduction
Nitinol Wire is a shape memory alloy made of nickel and titanium. It is a specialty alloy that can automatically restore its own plastic deformation to its original shape at a specific temperature. Its expansion rate is above 20%, fatigue life is up to 107, damping characteristics are 10 times higher than ordinary springs, and corrosion resistance is superior to the best medical stainless steel available. Therefore, it can meet the needs of all kinds of engineering and medical applications. Mekon can supply high-precision, competitively priced Nitinol wires with various specifications to suit your needs.
