Aluminum foam for sound absorption

pore size:0.9mm,1.6mm,2.5mm 
thickness:3mm,5mm 8mm,9mm,10mm
size:500x500mm or as per customer's request. 

Aluminum foam is made from aluminum die-casting, different with porous metal foam .It is
good sound absorption material, stable acoustic performance, easy processing, and use it to make various forms of suction sound body, muffler, sound structure, sound barriers, silencers room, acoustic enclosures, etc., can be directly facing the noise source, without any protective panels and other sound-absorbing fillers.
 
Average absorption coefficient ≥0.60 (125-4000Hz frequency range,); both board and spray gray water absorption properties do not change after the excellent acoustic performance.
 
Aluminum foam is currently no fibrous material in the world front and replacement products will not cause aging like after a similar fiberglass, mineral wool, rock wool, etc. by the high temperature environment into the sun and rain and dust flying cause secondary pollution of the atmosphere.
