Microcellular Closed Cell Aluminum Foams

Aluminum Foam is a modern structurally functional material that offers a wide range of good qualities. The aluminum foam can be separated into closed-cell aluminum foam and open-cell aluminum foam based on the pore structure, with each hole in the former being unconnected and each hole in the latter being connected.

Aluminum Foam products are known for their exceptional qualities, including their low weight, high sound absorption, high shock absorption, high absorption of impact energy, high electromagnetic shielding performance, excellent heat insulation, high temperature, fire resistance, and special environmental friendliness.

The term "open-cell aluminum foam" refers to aluminum foam having interconnected interior pores ranging in size from 1.0 to 8.0 mm and porosity ranging from 65% to 80%. Because of its metal characteristics and porous structure, through-hole aluminum foam is an excellent noise reduction material that can be utilized for an extended period of time under difficult working conditions and has good sound absorption and fire resistance. Through-hole foamed aluminum comes in a variety of flow resistances and through-hole apertures (through-hole ratios), and it can be engineered to minimize noise to NRC > 0.75 or fulfill fire protection grade A1 standards.

Closed-cell foam material: It has an independent cell structure, and the internal cells are separated from the cells by a wall film, and they are not connected to each other. The closed-cell foam material has extremely excellent impact resistance, resilience, flexibility, sound insulation, heat insulation, water resistance, vapor resistance, floating properties, etc.
