Material Description

1) Remark: CuNi3Si belongs to the hardenable, low-alloy copper alloys. Except a good electrical and thermal conductivity and corrosion resistance. CuNi3Si possesses a high fatigue and creep strength apart from good spring characteristics. Stength grade lie between F60 and F80. In the hardened condition CuNi3Si is insensitive to stress corrosion. The destabilization temperature is approx. 450 °C. In the low temperature range the strength continues to rise still. Manufacturing properties: warm and cold forming: well machinability: means soft soldering: well braze welding: means gas-schielded arc welding: means polishing bar: well Application: Use particularly as overhead line material such as clamps, latches, nuts, high-strength and corrosion resistant screws. For wires rope in the electrical building of overhead lines, for bushes, antifriction bearing cages, valve guide sockets and springs.
