What is aluminum foam?
Aluminum foam is a porous composite metal material with aluminum or aluminum alloy as the matrix and metal skeleton and pores as the composite phase. The performance depends on the metal matrix, porosity and pore structure.Aluminum foam is divided into two structural forms: open cell and closed cell.

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.
