Tungsten, Nickel and Copper/Iron Blend Alloys
Tungsten, Nickel and Copper/Iron Alloy (HD17BB)
Originally developed for boring bar applications, Mi-Tech Metals’ HD17BB provides the benefits of both iron and copper. While still an excellent choice for tooling, it is also recognized as a cost-effective alternative to traditional tungsten, nickel, and iron alloys. HD17BB meets the requirements for AMS-7725, AMS-T-21014, MIL-T-21014D, as well as the current ASTM-777-07 Class 1 specifications.
For detailed information on the unique strengths of our tungsten, nickel, and copper/iron alloy material, refer to the high-density alloys properties chart.
