Abstract (en)
A composite contact including a first layer composed of a Cu-Cr mixture wherein powder or granular Cr with an average particle diameter of 0.1 to 150 µm and powder or granular Cu with an average particle diameter of 0.1 to 150 µm are mixed at a rate of 15 to 60 wt% of Cr and the remainder of Cu, and a second layer composed of Cu. The first layer and the second layer are united with each other, while Cu of the first layer enters the second layer within a range from 20 µm to 100 µm from a boundary surface between the first layer and the second layer and Cu in the second layer enters the first layer within a range from 20 µm to 100 µm from the boundary surface.
