The aluminum foam materials have studied for the last 15 years in China, from laboratory experiments to industrialized scale. we can manufacture 800mm×2000mm aluminum foam board products. The essential parameters of our aluminum foam product are as follows, density: 0.3~0.6g/cm3; porosity: 77%~88%; pore diameter 5MPa. Some properties of aluminium foam materials were studied such as sound absorption, energy absorption, impact bending strength of aluminum (steel) plate/Al foam sandwich, etc.
