▎ 摘　　要

NOVELTY - Graphene manganese copper base damping material powder comprises manganese copper composite graphene powder, nickel powder, tin powder, rare earth metal powder and silicon-containing material. The manganese-copper graphene powder comprises manganese powder, copper powder and graphene, and the graphene is grown on the mixture of the copper powder and the manganese powder. The mass ratio of the copper powder is 18-38%, the manganese powder is 59-79%, and the graphene is 0.05-3%. USE - Graphene manganese copper base damping material powder for use in aerospace, military industry, automobile, construction and ocean engineering. Uses include but are not limited to missile, carrier rocket and aircraft. ADVANTAGE - The graphene manganese copper base damping material powder has good mechanical property and conductive performance. The graphene can reduce damping factor attenuation rate, improves the mechanical performance and electrical performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a preparation method of graphene manganese-copper-based damping material powder; (2) an alloy damping material.
