Nitinol Superelastic Bars are primarily made up of nickel and titanium, typically containing about 55–56% nickel and 44–45% titanium by weight, which is optimized to achieve superelasticity at room temperature. This well-balanced composition allows for stress-induced phase transformation, enabling recoverable strains of up to 8%. The material boasts high tensile strength, excellent fatigue resistance, a relatively low elastic modulus, and strong corrosion resistance. These mechanical properties ensure reliable performance under cyclic loading, repeated deformation, and challenging operating conditions.
