George Metals is a top-notch producer and supplier of high-end alloy materials in Houston, USA, providing high-grade **Nitinol Superelastic Bars** for top-performance engineering and medical use. Famous for its shape memory and superelasticity, Nitinol is designed to go back to its initial shape when deformed, and thus it is best suited for dynamic and precision-critical situations. George Metals holds strict quality control standards, accurate composition control, and guaranteed delivery. Supplying the aerospace, biomedical, robotics, and industrial markets, the company is relied on throughout the USA and worldwide for the supply of innovative materials designed to meet the complex needs of applications.
**Nitinol Superelastic Bar** is an alloy consisting chiefly of almost equal amounts of nickel (≈55%) and titanium (≈45%). The remarkable material demonstrates both shape memory and superelasticity, enabling it to be deformed extensively and restore itself to the original shape without residual strain. The product—**Nitinol Superelastic Bar**—has superior fatigue resistance, corrosion resistance, and tensile strength of up to 895 MPa. It comes in a range of diameters and finishes, with superelastic behavior usually active between 20°C and 40°C and therefore ideal for application at body or ambient temperatures.
