Fort Wayne Metals, Fort Wayne, Ind., manufactures premium medical grade Nitinol ASTM F2063 cold drawn coil into finished discrete lengths of superelastic bar typically 6 ft. long. Diameters range from 2.28 to 4.75 mm with either a natural forming oxide, or centerless ground and polished surface. Its Nitinol chemistry exceeds the governing standard.
Each medical grade of Nitinol material is comprised of near-equal atomic weight percentage of nickel and titanium. Our most common medical grade, NiTi#1, exceeds chemistry requirements set forth by ASTM F2063 for surgical implants. All incoming Nitinol raw materials are inspected to ensure they meet proprietary internal specifications for chemistry, ingot transformation temperature, material homogeneity, and microstructure.
Optimized to promote an exceptionally smooth and uniform surface finish quality, all wire products utilize a proprietary single and multicrystalline diamond drawing die technology. Medical grade Nitinol wire may be purchased in the cold worked (CW) or the super-elastic condition (SE) and after the correct super-elastic heat treatment will accommodate strain up to 8% without permanent kinking at body temperature.
