Beryllium Copper
Overview
C17200 is the highest-strength copper alloy commercially available. When heat treated, it achieves tensile strengths exceeding 200,000 psi while maintaining good electrical and thermal conductivity. It is non-sparking, non-magnetic, and resistant to fatigue.
As a C17200 beryllium coppersupplier, Triton Bronze & Metals stocks copper in round bar, flat bar, plate, and more — all cut to length and shipped from US mills. Certified mill test reports available to meet your quality requirements.
