Abstract Foam metal is a new type of structural functional material composed of metal matrix and a large number of
channels. It has excellent properties such as heat，sound，light and energy absorbing.Porous aluminum foam is the most
popular and most promising foam metal at present. As a "metal star"，aluminum foam has many excellent properties such
as small density，high temperature resistance，corrosion resistance，non-flammability，good weather resistance，low thermal
conductivity，strong electromagnetic shielding，energy absorption and noise reduction，and is widely used in automotive
industry，aerospace and construction industry and other engineering fields. The structural characteristics，application
properties and application progress of aluminum foam in engineering are summarized in this paper.
