ALUPOR™ VS Porous metals

Porous aluminium produced by replication casting differs from other metal foams. ALUPOR™ can serve as effective analogue of another aluminum foams, sintered bronze and steel, porous ceramic, etc. This is open cell permeable material with porosity 50-70%, high durability and variety of shapes and forms. The foam density and filtration degree can be changed in a wide range. The another technical features are presented below.
