Metal Rubber (MR) is a kind of new-style porous damping material. It is made of wires through choiceness, encircling, wiredrawing, weaving and molding by compression. The special production techniques make its characteristics incomparable, such as high damping, controllable porosity and strong environmental adaptability, besides it is easy to be fabricated into complex shapes. Thus MR can be widely used in many aspects such as damping，sound absorption, seal and thermal protection. The damping and sound-absorbing characteristics of MR material are studied in theory and experiment in the paper, and the applications of MR products are introduced.
