Starc Metals stands out as a top-notch manufacturer and supplier of Nitinol Superelastic Bars right here in Canberra, Australia. We specialize in high-performance nickel-titanium alloy products that are designed to meet the demands of modern applications. Our Nitinol Superelastic Bars are remarkable for their elasticity, flexibility, and durability, allowing them to bounce back to their original shape even after being significantly deformed. Thanks to their excellent fatigue resistance, corrosion resistance, and biocompatibility, these bars find their way into advanced engineering and medical fields. At Starc Metals, we prioritize precise composition control, a smooth surface finish, and consistent mechanical behavior, ensuring our products perform reliably even under dynamic and high-strain conditions.
When it comes to composition, our Nitinol Superelastic Bars are made up of about 55–56% nickel and 44–45% titanium, with slight variations in nickel content affecting the transformation temperature. This unique alloy boasts a tensile strength ranging from 895 to 1900 MPa and can recover up to 8% strain through superelastic deformation. Mechanically, Nitinol is known for its impressive fatigue life, a lower modulus of elasticity compared to steel, and outstanding resistance to corrosion and oxidation. Its ability to switch between austenite and martensite phases gives it those distinctive superelastic and shape memory properties.
