Fort Wayne Metals, Ind., manufactures wire products from several grades of Nitinol commonly used in medical applications, as well as Nitinol alloys for other applications. Each medical grade 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 grades are available in either the cold worked (CW) condition ready for heat treatment, or as straightened super-elastic (SE) wire.
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 multi-crystalline 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.
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 4.75 mm (0.187 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.
