Flame Retardant, Thermal Insulation, Lightweight Applications

• Aluminum foam density is only about 0.1 and 0.4 times that of aluminum, and the specific stiffness can be up to 1.5 times that of steel. Aluminum foam sandwich panels have a very large potential market, such as railroad train cars, containers, heat insulation, sound insulation, fire prevention, anti-virus components on the application of the expected huge demand.
• Modern building functions are diverse and complex, the requirements of environmental protection, safety, energy saving, foam aluminum light weight, high stiffness, with the inherent advantages of metal, flame retardant effect is very ideal, widely used in energy-saving building components, such as heat-insulating walls, fire-insulating doors, elevator interior decorative panels, energy-saving mobile homes.
• Aerospace field, widely used honeycomb structure material, but the cost of honeycomb structure material is relatively high. Aluminum foam sandwich panels are similar to honeycomb structural materials in that they have low density and high specific strength, but aluminum foam has the advantage of manufacturing cost, and will most likely replace honeycomb structural materials in future development.

Areas of Application

With the development of science and technology, as a new type of material integrating structural and functional materials, the application of aluminum foam is constantly expanding and extending, and the developed countries have successfully applied the noise isolation, vibration damping and energy absorption as well as multifunctional compatibility of aluminum foam in many fields.

• Highway and Railroad Sound Barrier Application Fields
• Military Applications
• Automobile Industry
• Train, Ship Applications
• Aerospace
• Construction Industry

Sound Insulation and Noise Reduction

Energy-absorbing Cushioning Material

The damping performance of aluminum foam can reach 5-10 times of aluminum. A piece of aluminum foam with a porosity of 84% can absorb more than 2.5MJ/M3C energy when 50% of its deformation occurs, and the energy absorption effect is far more than that of other shock absorbing materials. Transportation, aviation industry, machinery manufacturing and other products of heat insulation, sound insulation, shockproof, energy-absorbing components can be used foam aluminum materials.

• Vehicle crashworthiness in the transportation industry is a big problem involving life and property safety, and the foam aluminum energy-absorbing boxes at both ends of the high-speed train carriages greatly improve the impact buffer effect of the carriages.
• Aluminum foam material used in the automobile manufacturing industry used in energy-absorbing components and sound-absorbing components, such as bumpers and silencers, aluminum foam impact beam to meet the requirements of the kinetic energy absorption of the collision, is conducive to solving the problem of automobile collision avoidance.
• Aluminum foam material used in the manufacture of aviation equipment buffer cushion to protect the airborne safety smooth, large ship decks, bridge collision avoidance, elevator fall buffer and other material applications can improve the buffer capacity of the fall, impact, to ensure that the facilities, personnel safety protection ability.

Electromagnetic Shielding

Aluminum foam electromagnetic shielding performance is excellent, the radio frequency 200MHz below the electromagnetic wave, the shielding effectiveness of 90dB. 20mm thick iron plate with foam, the shielding of electromagnetic waves for 50dB, and the same thickness of the foam aluminum, shielding electromagnetic waves for 90dB, the weight of the iron plate is one-fiftieth. Available in military products, electrical products, sound absorption and anti-magnetic components, such as tanks, submarines shell sandwich panels. The structural advantages are as follows:

• Omni-directional fine electromagnetic circuit
• Omni-directional refraction, scattering and absorption
• Continuous change of propagation medium, high interface loss
• Skin effect of single-layer materials, easily saturated
