Nitinol is the intermetallic phase NiTi with an ordered cubic crystal structure that differs from that of titanium and nickel and consists of about 55% nickel, the rest being titanium. The alloy can be used up to 650 °C, is corrosion-resistant and high-strength, but can be pseudoelastically deformed up to approx. 8%.
Because of the so-called memory effect, it is used in medical technology.
