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.*0 (*******0Hz 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.
