Porous metals or metallic foams are engineering materials with a unique combination of physical and mechanical properties. They have been developed during recent years used  in various fields. It is expected a growth in application of these type of materials due to their novel properties .

The properties include high specific strength, good thermal conductivity, electrical conductivity, compression damping , and excellent acoustic properties. Open-cell metallic foams have been used successfully  in filtering applications, as well  heat exchanger.

ACECR Mashhad branch, for the first time in Iran, could set up a pilot for production of close cell Aluminum foam in 2011.

 Some of the main application of metal foams are listed as follows:

-    Automotive industry as an energy absorption

-    Structural industry as a sound absorption and light materials

-    Heat exchanger in Power plants and refineries industry

-    Defense industry as an energy absorption and resistant to explosion

-    Catalyzer and rechargeable battery

-    Biomaterials as porous implants   

-    Filters and separators in polluted environments and industries

-    Aerospace industry as a light and energy absorption materials

-    Casting industries as a light core

-    Silencer in industrial equipment
