CuCo1Ni1Be—CW103C (DIN 2.1285) 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 45-60
percent of copper with ultimate tensile and hardness properties
approaching 140 ksi and RB 100 respectively, all of its properties
are quite the same as CuCo2Be-C17500 and CuNi2Be-C17510.
Typical Physical Properties: Density (g/cm3): 8.83 Density before
age hardening (g/cm3): 8.75 Elastic Modulus (kg/mm2 (103)): 14.10
Thermal Expansion Coefficient (20 °C to 200 °C m/m/°C): 17 x 10-6
Thermal Conductivity: 209 W/m • oK at 20 C Melting Range (°C):
