Battery Making Aluminum Al Metal Foam For Experimental Materials

Aluminum foam has many special properties. It can be widely used in aerospace, aviation, high-speed trains, urban rail trains, shipbuilding, high-speed railways, construction, tunnels and noise barriers along the way.

It has light weight, high sound absorption, high shock absorption, high absorption energy, high electromagnetic shielding performance, excellent heat insulation, high temperature resistance, and non combustible combustion characteristics. It has unique environmental friendliness.

*Low density and light weight: the density range is 0.5-0.8g/cm3, which is about 15% of aluminum when the density is the lowest compared with compact aluminum;

*Heat resistance: the temperature can reach 660 degrees Celsius, the melting point of the base aluminum;

*Rigidity: The bending specific stiffness can be better than that of steel. It is not malleable like dense metal. Under strong pressure, its porous structure will not reach the level of destruction and will not deform;

*Impact resistance: It is not directional like honeycomb, nor is it resilient like polymer materials. It is longer than absorbing impact energy;

*Permeability: open-cell aluminum foam pores are connected, three-dimensional opening, breathable and liquid-permeable;

*Sound absorption performance: When the sound wave frequency is between 125---2000HZ, the maximum sound absorption coefficient can reach 0.95, and the noise reduction coefficient exceeds 0.4.

*Thermal insulation performance: The thermal conductivity coefficient is about 1/400 of pure aluminum;

*Electromagnetic shielding performance: When the electromagnetic wave frequency is between 2.6-18GHZ, the electromagnetic shielding capacity of foamed aluminum can reach 60-90dB.

*Resistivity: 100 times that of pure aluminum;

*Corrosion resistance: good weather resistance, low moisture absorption, non-aging, non-toxic.
