C17500 CuCo2Be Beryllium Copper Tube
C17500 Cobalt Beryllium Copper
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.
