Sintered porous metals with traits of metals and porous materials have many attractive properties, such as higher mechanical strength, good solderability, corrosion resistance, and excellent machinability. Its application and properties quickly expand resent years. Recently, the research of porous metal material has entered to a stirring period, and a series of porous metals with various materials, new pore structure, different physical and chemistry properties have been developed and found their actual applications soon. With the development of modern industry, the development of porous metal material is now tending higher properties and multi-functionalization, embodied in gradient pore structure, micronized pore size, composition of various material, integration of preparation and application research, and so on. In the comprehensive view, the porous metal is a sort of attractive materials with excellent sustainable vitality.
