Nitinol Shape Memory Bars are primarily made of nickel and titanium, usually in nearly equal proportions, which gives the material its remarkable shape memory and superelastic qualities. This alloy is known for its high elasticity, excellent fatigue resistance, and the ability to return to its original shape when heated or unloaded. Its mechanical properties include high tensile strength, impressive flexibility, and stability across various temperature ranges. These features enable Nitinol bars to perform reliably under dynamic stress, repeated cyclic loading, and complex operational conditions.
