Abstract: A new idea of design and manufacture of metal-based materials possessing both high damping and good mechanical properties was proposed. The key of the idea is the combination of fining restriction-damping structures, using all mechanisms and taking advantages of different materials. Based upon this idea a foam ZA27 was prepared by the technology of prefabricated salt-mass  centrifugal seeping foundry, its tensile strength and compressive strength are  83~119 MPa and 100~189 MPa, respectively. The damping properties of the foam ZA27 increase remarkably after the carpenter pastern or rosin (the dampingincreased materials) was immerged into  it, which approaches to the level of viscous-elastic polymer materials ( Q-1≥20×10-3 ).
