Fort Wayne Metals manufactures numerous medical grades (most common NiTi#1, NiTi#2 and NiTi#4) of Nickel-Titanium or Nitinol wire products available in either the cold worked (CW) condition ready for heat treatment or as straightened super-elastic (SE) wire. Multiple surface treatments along with varying thermal and mechanical properties are also available.

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 use in surgical implants. At Fort Wayne Metals, 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.
