Graphene reinforced copper-based composite contact material and method for producing the same

摘要

The present invention provides an oxide powder: 0.01 to 10% by mass, a carbide powder: 0.01 to 2% by mass, and a balance: a copper powder or a copper alloy powder coated with graphene having a thickness of 10 nm or less. A graphene-reinforced copper-based composite contact material and a manufacturing method thereof have been disclosed. This copper-based composite contact material has the advantages of low contact resistance and stability, and excellent arc wear resistance and welding resistance. Can be applied to.
