Use of aluminium foam with different specific gravity
Serial number | Specific gravity(g/cm3) | Size(mm) | Main Uses |
1 | 0.25~0.4 | 1200×600×h according to customer requirements | Sound-absorbing material, marble composite board, internal and external decorative composite board, heat-insulating wall material |
2 | 0.4~0.6 | Impact-resistant materials, composite panels for car body, sound-absorbing materials, marble composite panels, internal and external decorative composite panels | |
3 | 0.6 or more | Impact-resistant materials |
Product application fields:
As aluminium foam products have many special properties, they can be applied in aerospace, aviation, high-speed trains, urban rail trains, shipbuilding, high-speed railways, construction, tunnels and sound barriers along the way, etc. They have the properties of lightweight, high acoustic absorption, high vibration damping, high absorption of impact energy, high electromagnetic shielding, heat insulation, fire-resistant, and non-combustible properties. It is environmentally friendly.
