CuCo1Ni1Be:Cobalt Nickel Beryllium copper alloy contains approximately 1% cobalt ,1% Nickel and 0.5% beryllium .After hit forging and heat treatment processes this material gains considerably hardness , electrical and thermal conductivity as well . It is possible to have different combinations of electrical conductivity and hardness by changing the heat treatment conditions .
CuCo1Be 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 140ksi and RB100 respectively ; all of its properities are quite the same as CuCo2Be-C17500 and CuNi2Be-17510 .
