Aluminum foam applications
As ships' specifications for silence and lightness get more stringent, so do material requirements, particularly for ultra-light constructions and multifunctional materials. Foamed aluminum, as a novel type of multifunctional material, has lightweight, high specific stiffness, sound absorption, and sound insulation, heat insulation, shock resistance, impact resistance, outstanding electrical performance, and recyclability, among other properties. It's employed for weaponry, equipment, and civilian use on the sea, land, and air. It has a wide range of applications. Energy-absorbing and shock-absorbing materials, sound-absorbing materials, electromagnetic shielding materials, heat-exchange materials, heat insulation materials, and filter materials are some of the applications of foamed aluminum as a structural and functional material. Foam aluminum is widely used in the rail transit industry for heat insulation, sound insulation, and energy absorption in carriages and containers, as well as fire-proof and anti-virus parts, due to its low density, high rigidity, sound insulation, heat insulation, fire resistance, energy absorption, and lack of toxic gas when heated.
Sound insulation, sound absorption, and energy absorption properties of foamed aluminum are used in environmental protection fields in urban construction, such as sound insulation screens; energy absorption and sound absorption components, such as bumpers and silencers, are used in automobiles manufacturing. Foamed aluminum is commonly used in energy-saving buildings, such as heat-insulating walls, fire-resistant and heat-insulating doors, and energy-saving mobile homes, due to its low density, high stiffness, and low thermal conductivity. Foamed aluminum's sound absorption and antimagnetic qualities can be used in military applications such as armored vehicles and submarine shell sandwich panels. Foamed aluminum can be utilized as heat-insulating, sound-proofing, shock-proofing, and energy-absorbing components in machinery manufacturing, aviation, and other industries. Foamed aluminum, as a functional material, has been commercialized in developed countries.
