What is Aluminum Foam, and what are the performance characteristics?
Foam aluminum is a kind of porous material with countless bubbles distributed in the Metal matrix. Foam aluminum, from its name, is composed of an aluminum metal structure with distributed bubbles, and the whole is very fluffy. Aluminum foam is prepared by various methods, mainly solid metal sintering, liquid metal solidification, and metal deposition methods.
Aluminum foam mainly has the characteristics of lightweight, sound absorption, color, high freedom of process and optical design, easy processing, physical properties, and a variety of properties etc., and is widely used in many fields.
The application of aluminum foam in automotive lightweight
The density of aluminum foam is very small, only 0.2~0.4g/cm3, in addition to being much lower than aluminum alloys, titanium alloys, steel, etc., and even lower than the density of wood. In automotive lightweight manufacturing, aluminum foam has a lighter quality, higher strength-to-weight ratio, and has high energy absorption characteristics, damping characteristics and vibration absorption characteristics, can achieve the sense of automotive silence; will be filled with aluminum foam in the two high-strength sandwich panels made between the outer plate can be used for bumpers, longitudinal beams and some support parts when you can increase the capacity of the impact of the energy-absorbing capacity, in the lightweight at the same time, to improve the safety of the impact.
In addition to its application in automotive lightweighting, aluminum foam also has abundant applications in the following scenarios:
Building Decoration and Home Fields
Building Exterior and Interior: Aluminum foam can be used as a material for the exterior of a building, providing excellent heat and sound insulation. Meanwhile, its unique artistic effect and processability make it an ideal choice for interior ceiling and wall decoration.
Composite flooring and spacer walls: Composite flooring and spacer walls made with aluminum foam panels not only provide excellent sound insulation but also effectively reduce building weight and improve the energy efficiency of the overall structure.
Transportation & Infrastructure
Transportation interiors: In trains, ships, and other vehicles, aluminum foam can be used for carriage side linings, partition walls, etc., providing sound insulation, heat insulation, and lightweighting effects. For example, the use of aluminum foam panels in the side linings of high-speed trains can significantly reduce operating noise.
Sound barriers and sound-absorbing materials: aluminum foam sound-absorbing panels can be used as sound barriers on elevated roads, viaducts, highway tunnels, undersea tunnels, and other places to effectively reduce noise pollution.
Military and Protection
Composite Armor: The new composite armor consists of a ceramic sheet, aluminum foam, and an aramid fiber plate, which uses the energy absorption of aluminum foam to enhance the armor’s protective ability.
Explosion-proof equipment: Aluminum foam can be used in the army’s main battle tank composite armor, armored vehicle explosion-proof chassis, etc., as well as the navy’s composite decks, ship compartments, etc., due to its lightweight, high strength, and energy-absorbing properties.
Aerospace
Structural components and thermal protection: Aluminum foam can be used to make structural components and thermal protection systems in the aerospace field. Its lightweight, high strength, and excellent heat-resistant properties help to improve the overall performance of the aircraft.
Electronics and communication
Electromagnetic wave shielding: Aluminum foam has a good shielding effect on high-frequency electromagnetic waves, and can be used to solve electromagnetic shielding problems, such as solving electromagnetic shielding problems for the world’s scientific research device, “artificial sun” ITER.
Other fields
Energy Absorption and Collision Avoidance: Aluminum foam has high energy-absorbing properties, which can be used to make energy-absorbing boxes, collision beams, and other automobile safety parts to enhance the safety of vehicles.
Artwork and decoration: The lightweight, easy processing characteristics and unique artistic effect of aluminum foam make it an ideal material for sculpture, installation art, and other artwork.
