Broad range of precisely defined pore sizes


Porous aluminium has a broad range of precisely defined pore sizes / filter degrees, a very good permeability (all cells are open), a High specific surface area, low weight and high strength. Porous aluminium is temperature-resistant and has a good thermal conductivity.

Our products made of porous aluminum have – thanks to innovative and relative simple manufacturing technology – an excellent quality-price ratio. The production costs - and consequently the product costs - are considerably lower than those of equivalent products made of sintered metal (sintered filters, sinter metal filters and sintered filter elements, sintered silencers etc.) and ceramic materials.
