▎ 摘　　要

NOVELTY - An electric contact material comprises 0.1-3 wt.% nickel-plated graphene, and 97-99.9 wt.% copper alloy comprising 0.15-0.5 wt.% bismuth, 0.1-3 wt.% zinc, tin, aluminum, nickel and/or silver, preferably zinc, aluminum and/or nickel, and remaining copper. USE - Electric contact material (claimed). ADVANTAGE - The electric contact material has no reduction in electroconductivity and thermal conductivity, high hardness, and excellent impact mechanical shock resistance and arc-ablation resistance, provided by the nickel-plated graphene framework. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of electric contact material.
