OLIN7025

Main application
Connectors, Springs

Characteristics
Mg-modified Corson alloy (Cu-Ni-Si)
Good in bend formability and high electrical conductivity for connectors.
Particularly suitable for replacement of beryllium copper alloy, with eco-friendliness and cost competitiveness for its chemical composition.
Very good stress relaxation and heat resistance properties at elevated temperature.
No heat treatment required for hardening.
