Sound box Properties:
Acoustic performance: perforated closed-cell foam aluminum plate can be made into a high acoustic absorption rate acoustic panels. When the opening rate is 1%~3%, the sound absorption rate. Sound absorption rate measured by standing wave method, in the range of 1000Hz to 2000Hz, the sound absorption rate of 40% to 80%.
Foam aluminum sound insulation role: foam aluminum sandwich panel production sound insulation board, 20mm thick, sound insulation: 20 ~ 40dB.

Weathering Performance:
Corrosion resistance: one year exposure in the marine atmosphere, no obvious abnormality; accelerated corrosion conditions, water spray salt spray test for 2 years without abnormality; indicating that the corrosion resistance of aluminum foam is very good.
No moisture absorption: the moisture absorption rate of aluminum foam is 0.0%. There is no hygroscopic phenomenon, and the acoustic performance will not be reduced due to humidity.
Heat-resistant/non-combustible properties: Aluminum foam softens only at a high temperature of 600°C, making it a non-combustible material.
Thermal insulation properties: The thermal conductivity of aluminum foam is 0.25~0.62W/m.K, which is comparable to that of marble, and has good thermal insulation properties.
Thermal stability: the linear expansion coefficient of aluminum foam is 1.934*10℃, which is comparable with concrete, and it is not easy to be deformed by heat.

Mechanical Properties:
Mechanical properties: compressive strength: 3 ~ 17MPa; flexural strength: 3 ~ 15MPa; tensile strength: 2 ~ 7 MPa;
Cushioning properties: energy absorption up to 8J/cm3 ~ 30J/cm3, aluminum foam can absorb energy through deformation, is an excellent impact energy absorption material.
Damping performance: tested by the Institute of Solid State Physics, Chinese Academy of Sciences, aluminum foam internal consumption factor Q-1 reaches 6 × 10-3.

Mechanical Properties:
Aluminum foam is used in various fields, based on a porous lightweight silver-white metal materials, with excellent processing characteristics, can be sawed, cut, planed, milled, etc., easy to be processed into plates, strips, rods, and a variety of shaped parts.

Green Environmental Protection:
