Cobalt Beryllium Copper

Cobalt Beryllium Copper is primarily utilized in the industry applications that require most highly thermal.

CuCo2Be---C17500 (CDA 175) Cobalt Beryllium Copper is primarily utilized in the industry applications that require most highly thermal or electrical conductivity, which features a cobalt alloying addition (2.40-2.70%). C17500 also Offers good strength and hardness characteristics coupled with conductivity in the range of 45-60 percent of copper with ultimate tensile and hardness properties approaching 140 ksi and RB 100 respectively.

Typical Application for C17500 Cobalt Beryllium Copper Alloys: Electrical Industry:Fuse Clips, Switch Parts, Relay parts, Connectors, Spring Connectors Fasteners:Washers, Fasteners Industrial:Springs, Seam Welding Dies, Resistance Welding Equipment, Resistance and Spot Welding Tips, Tooling for Plastic Moulds, Die--Casting Plunger Tips.
