Next-generation Cost-Effective copper alloy. The world's first Cu-Zn based alloy contributing to the excellent terminal performance and low cost. It is an innovative material that overcomes the deterioration of the spring properties under the high temperature or corrosive environment which was a weak point of the conventional Cu-Zn system. It contributes to the demonstration of the excellent terminal performance and low cost.
A copper alloy for automotive general purpose terminals. When it is excellent in the strength and the bending workability, it also has stress relaxation resistance characteristics. It has characteristics that can be applied to various applications.
In-vehicle terminals, consumer terminals, bus bars, spring materials, press-fit terminals
