An alternative to sintered metals and metal foams

Open celled porous metal
Different pore sizes
Volume porosity > 55%

Low density
High strength
Very good permeability

High operating temperature
High specific surface area
Good thermal conductivity

Porous aluminum is manufactured through casting. Being a high porosity metal, it is permeable over the entire surface. It has several advantages compared to sintered metals and metal foams: broad range of precisely defined Filter grades / pore sizes, homogeneous structure, high strength, extra strong cast interface between porous and non-porous parts.

The industrial production of porous aluminum started in 1989. Since then this porous metal has been used in a wide range of applications: filter and filter elements, silencers, heat exchangers, lightweight construction components and many other applications.
