Open cell or close cell alumimum foam porous metal foam
● Excellent energy absorption and sound absorption
● wide application: building material,exterior walls, interior walls, ceilings,
Description
Foamed aluminum, the new engineering structure material,is made by adding additives to pure aluminum or aluminum alloy and undergoes a foaming process. It has both metal and bubble characteristics.According to different structure of aluminum foam, it is divided into open-cell aluminum foam and closed-cell aluminum foam.
Open cell aluminum foam
● The pores are connected to each other, and the metal aluminum has a three-dimensional network structure；
● Due to its permeability or open porosity, it can be used for applications requiring vibration and sound absorption.
Closed cell aluminum foam：
● The pores are closed to each other, and the metal aluminum has a polyhedral wall structure.
● Due to its excellent mechanical properties, it is mainly used as a structural material to bear loads and absorb energy.
Physical characteristics
The performance of aluminum foam mainly depends on the shape and distribution of pores,including the type of pores (open or closed), shape, distribution, structure (pore size, porosity, specific gravity, etc.)

Applications
Thanks to the special production process, there are more styles of foamed aluminum and a wider range of applications. It can be used to cover exterior walls, interior walls, ceilings, floors, and stairs required for architectural decoration. area.
The porous structure of foam aluminum absorbs impact energy. This feature can be used to prevent collision during transportation.
Aluminum foam has the effect of sound reverberation and decoration.
