Spherical Open Cell Aluminum Foam Board for Construction (100mm×100mm×5mm)

Special Properties Weather resistance Corrosion resistance—Exposure to the Marine atmosphere for 1 year, no obvious abnormalities. Accelerating aging of salt spray for 2 years, no obvious abnormalities. Spraying anti-corrosion materials on the surface can improve the ability to prevent corrosion further. Hygroscopicity—No hygroscopic phenomenon in aluminum foam, no performance degradation due to moisture absorption. Thermal insulation—Thermal conductivity of aluminum foam is 0.25-0.62W/m·K, it has good heat insulation performance. Thermostability—Linear expansion coefficient of aluminum foam is 19.34*10-6/℃, not easy to defoam. Sound insulation performance High sound absorption plate can be made by drilling closed cell aluminum foam plate. When the opening rate is 1-3%, the absorption rate is the highest. The sound absorption rate is 40-80% In the range of 1000-2000Hz. Aluminum foam sandwich board as sound insulation board, thickness 20mm the sound insulation 20-40dB.

• Open Cell AluminumFoam 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 haslight 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.
• Aluminum foam, based on aluminum, is an isotropic highly porous metallic material with a cellular structure containing more than 70 vol.% of pores. As its special structure and the original characteristics of aluminum, aluminum foam has the properties of low density, good corrosion, wear resistance and low thermal expansion which can be widely used in lightweight structural components, shock or sound absorbing products.
