▎ 摘  要

NOVELTY - Graphene reinforced copper-rare earth-based electrical contact material comprises 0.1-3 wt.% graphene and 97-99.9 wt.% copper-rare earth alloy. Copper-rare earth alloy rare earth content is 0.05-3 wt.%. USE - Graphene reinforced copper-rare earth-based electrical contact material. ADVANTAGE - The material has improved hardness, wear resistance, impact resistance, fusion resistance, welding properties and oxidation resistance, and reduced arc burning loss capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of graphene reinforced copper-rare earth-based electrical contact material comprising crushing copper-rare earth alloy to 200-300 mesh, adding graphene powder, mixing, molding, cold forming, and sintering.
