C17500 CuCo2Be Beryllium Copper Plate

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.
