durable aluminum foam sound barrier

Acoustic Barrier Aluminum foam

21C is the aluminum foam day beyond semiconductor in 20C and

automobile in 19C.

The cutting-edge technology named aluminum foam is applicable throughout

various industries all over the world

What’s aluminum foam?

Aluminum foam is new concept metal material which is foamed in sponge shape after

melting aluminum ingot with various chemical ingredients and has many pore cells

inner structure.

Porous materials feature much lighter, improved energy absorption, lower conductivities

than original metal materials. Aluminum foam has broad applications and excellent

sound absorptivity and permeability of liquid, air, etc.

Aluminum foam can be applied to aerospace section needed to the thermostable state

Over 200°C and recyclable.
