Neil Metals, based in Kolkata, India, is a dedicated manufacturer and supplier of Nitinol Superelastic Bars, providing cutting-edge material solutions for industries that demand exceptional flexibility, shape memory, and biocompatibility. Nitinol, a nickel-titanium alloy, is renowned for its remarkable superelastic and shape memory characteristics, making it perfect for specialized engineering and medical uses. Neil Metals offers Nitinol Superelastic Bars in various diameters and specifications tailored to meet client needs. With a strong emphasis on quality control, advanced production methods, and a customer-centric approach, Neil Metals caters to high-tech sectors with dependable, high-performance Nitinol products.
These Nitinol Superelastic Bars consist of about 55% nickel and 45% titanium. This nearly equal mix allows the alloy to undergo significant deformation and then spring back to its original shape without any lasting strain, thanks to a reversible phase transformation between austenite and martensite structures. The bars showcase outstanding elasticity, boasting a tensile strength of around 895–965 MPa and an elongation of over 10–15%. Their superelastic properties kick in at or near body temperature, making them particularly well-suited for medical applications, all while ensuring corrosion resistance and excellent fatigue performance.
