Product Parameters
The aluminum foam produced by our company is processed by foaming process after adding additives to pure aluminum or aluminum alloy, which has the dual characteristics of metal material and foam material at the same time.

noise barrier (0)

Material properties and parameters are as follows
1. Density 0.2~0.5g/cm3, which is 1/5~1/10 of pure aluminum density, porosity 80% or more.
2. Sound absorption performance: good low and medium frequency (800Hz) sound absorption performance.
3. sound insulation performance: 20mm thick foam aluminum sound insulation performance of 30dB or more, the frequency can reach 10000Hz.
4. Compressive performance 2.5~16.0MPa, flexural performance 1.9~22.0MPa.
5. Energy absorption performance: high energy absorption performance with 0.5~0.6g/cm3, can reach 4~5MJ/m3
6. Electromagnetic shielding performance: superior electromagnetic shielding material, within 200MHz can shield 90dB
7. Heat transfer performance: lower thermal conductivity
8. Damping performance: the higher the energy absorption performance, the better the damping performance of aluminum foam sheet.
