Fort Wayne Metals manufactures premium medical grade ASTM F2063 cold drawn coil into finished discrete lengths of superelastic bar in typically two meters (6 ft). Diameters range from 2.28 mm (0.090 in) to 3.81 mm (0.150 in) with either a natural forming oxide or centerless ground and polished surface. If your Nitinol product need falls outside of the standard medical grade material or the available product forms, please contact one of our Nitinol application sales engineers. Our Nitinol chemistry exceeds the governing standard (ASTM F2063)
