Aluminum foam is a new kind of porous composite metal material, use aluminum or aluminum alloy as matrix, composed of a metal skeleton and air. This material has many cellular structure and holes. The special structure of porous metal of aluminum foam determines its superior performance in all aspects.
Add the foaming agent to the molten aluminum liquid with a certain viscosity and constantly stirred. The foaming agent is decomposed by heat to produce gas and form bubbles in the liquid aluminum, preventing bubbles from escaping and cooling the liquid aluminum, then aluminum foam can be obtained.
It has low density, high impact absorption ability, high temperature resistance, strong fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, high forming accuracy, surface coating.
It is a very important new material for military, ship weight reduction, automobile collision prevention, sound insulation and other fields
