CuCo1Ni1Be—CW**3C Cobalt Nickel Beryllium Copper

CuCo1Ni1Be—CW**3C (DIN 2.***5)Cobalt Nickel Beryllium Copper Alloy contains approximately 1% Cobalt, 1% Nickel and 0.5% Beryllium. After hot 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；CuCo1Ni1Be also Offers good strength and hardness characteristics coupled with conductivity in the range of ****0 percent of copper with ultimate tensile and hardness properties approaching **0 ksi and RB **0 respectively, all of its properties are quite the same as CuCo2Be-C****0 and CuNi2Be-C****0.
