▎ 摘　　要

NOVELTY - Oil-impregnated bearing material comprises 8-11% tin powder, 0.01-1% graphene powder or composite graphene powder, 1-3% composite graphite powde, and rest is copper powder and unavoidable impurities. USE - Oil-impregnated bearing material used for automobile lamp motor. ADVANTAGE - The oil-impregnated bearing material which improves material strength more than 50%, greatly improves anti-attrition property, has anti-friction performance, small friction coefficient, so as to ensure the service life of the automobile lamp motor reach more than 1000.
