Louis Metals offers C17200 bars and rods with one of the highest strengths of copper alloys. These bars are available in tempers such as T651, conforming to ASTM B194 standards, and are best suited for parts needing maximum hardness, fatigue strength, and wear resistance. Their finish is smooth, and their performance is consistent, so they are used where tooling, aerospace, or industry needs them.
C17200 has 1.8–2.0% beryllium content and can be precipitation-hardened to tensile strengths of up to 1400 MPa. Conductivity falls in the range of 20–25% IACS. It has high hardness, nonmagneticity, and is non-sparking, with good thermal stability and toughness.
