Product Description

Henan Chalco Aluminum is a high-tech enterprise specializing in R & D and production of new type of porous aluminum foam. In China, the first development of high absorptive pore porous foam aluminum is put into use, and the production of porous aluminum foam NRC can reach over 0.95. The shape of the plate produced is beautiful. At the same time, the strength of the sheet can meet various engineering needs, such as the tensile strength of B-type 4MM sheet can reach 8 MPa, the thinnest thickness can be more than 2 MM, the thickest can be 100 MM, the company also produces aluminum fiber sound absorber, which NRC can be 0.7-0.8, the weight of each square meter is usually between 1.5-2 KG, the length is arbitrary, can be sheared, can be curled, the thickness is usually 1.35-3 MM. Between them, it has very good toughness.

Porous aluminum foam has excellent performance in sound absorption, filtration, noise reduction, heat transfer, mold manufacturing and so on. The detailed properties are as follows:

Small cell porous aluminum foam
Pore Characteristics and Volume Density	Main aperture: 0.9mm, 1.6mm, 2.5mm three specifications, commonly used specifications are 1.6mm aperture. Porosity: 60-80% (68-78% at 1.6mm pore size) Porosity: 85-95% (90-95% at 1.6mm aperture) Volume density: 0.5-1.10g/cm3 (0.60-0.85g/cm3 with 1.6mm aperture)
Combustibility	Determination according to GB/T5464 (Shanghai Fire Product Quality Supervision and Inspection Station) The combustion performance of sound absorber meets the requirement of GB8624 non-combustible material (Class A): it belongs to non-combustible material.
