Abstract:The effects of the elements of zinc and aluminium on Ms point damping and mechanical property of Mn-Cu alloy were studied. The relations between the alloy components with damping property and mechanical property were also discussed. So a kind of high damping, high strength Mn-Cu matrix alloy (ZMnD-1J) was exploited, whose best constituent is Mn 50%, Zn 5%, Al 2%, and Cu the balence. The typical properties SDC=44.5%, σb=678 MPa, δ=24.1%. The damping capacity of Mn-Cu high damping material is high, meanwhile its mechanical properties are comparable with that of ZGD345-570. It can be used as structural material.
