Classic Aluminum Foam
(Semi-Closed cell/ Closed Cell)
Density: 0.25 g / cm3 ～ 0.85g / cm³, which is 1/30 of iron, 1/10 of aluminum, and 1/4 of wood;
Porosity: 68% ～ 90%;
Aperture: uniformly distributed 0.5-10mm, main aperture size depends on density;
Product specifications: 2400mm * 800mm * H or customized production according to customer requirements.
Closed-cell aluminum foam thickness 6-200mm. Semi-open-cell aluminum foam thickness 6-10mm
Corrosion resistance: exposed to the marine atmospheric environment for one year without obvious anomalies; under accelerated corrosion conditions, the water spray salt spray test shows it has no anomalies for 2 years; indicating that the aluminum foam has good corrosion resistance.
Non-hygroscopic: The aluminum foam has a moisture absorption rate of 0.0%. There is no hygroscopic phenomenon, and the acoustic performance will not be reduced due to moisture.
Heat resistance / non-combustibility: Foamed aluminum softens only at 600 ℃, and is a non-combustible material.
Thermal insulation performance: The thermal conductivity of foamed aluminum is 0.25 ~ 0.62W / m.K, which is equivalent to marble and has good thermal insulation performance.
Thermal stability: The linear expansion coefficient of aluminum foam is 1.934 * 10 ℃, which is equivalent to concrete, and is not easy to deform when heated.
Mechanical properties: compressive strength: 3-17MPa; flexural strength: 3-15MPa; tensile strength: 2-7MPa;
Cushioning performance: Energy absorption can reach 8J / cm³ ～ 30J / cm³, aluminum foam can absorb energy through deformation, it is an
excellent impact energy absorbing material.
Damping performance: After testing by the Institute of Solid State Physics, Chinese Academy of Sciences, the internal friction factor Q-1 of aluminum foam reaches 6 × 10-3.
Aluminum foam is widely used in various fields. It is a porous, light-silver-white metal material with excellent characteristics for easy processing. Can be made into Bars and various shaped parts.
Green and environmental protection
Non-toxic: Aluminum foam is a material composed of metal and pores, which is non-toxic itself and does not emit toxic gases at high temperatures.
Recyclable: The main chemical composition of aluminum foam is aluminum alloy and its oxide, which can be recycled 100% without causing any pollution to the environment.
Electromagnetic shielding: electromagnetic shielding (below 200MHz) shields the electromagnetic screen 90dB and has excellent electromagnetic shielding performance.
As aluminum foam products have many special properties, they can be widely used in aerospace, aviation, high-speed trains, urban rail trains, shipbuilding, high-speed rail, construction, tunnels and sound barriers along the way. Shock, high impact energy absorption, high electromagnetic shielding performance, excellent heat insulation, high temperature resistance, fire resistance and non-combustibility characteristics. With unique environmental friendliness.
