porous aluminum

an option for sintered metal and metal foam

Product description

Porous aluminium is a high porosity metal which is permeable over the entire surface. Aluminium is cast together with crystal salt. Afterwards the salt is washed out. The salt grains and their contact points are thus replaced by pores.

Porous aluminum has a unique combination of material properties:
– permeable over the entire volume, all pores are open
– every shape and size according to customer needs
– 6 standard types of pore sizes
– high strength thanks to cast structure
– low weight thanks to 50% volume porosity (number of pores in the volume)
– homogeneous distribution of the pores over the entire volume
– high thermal conductivity
– high heat capacity
– the manufacturing technology is innovative and relatively simple, fundamentally different from the production technologies of sintered metals and metal foams

Thanks to the unique combination of material properties, porous aluminum is perfectly suitable for the following applications:
· Filtration: compressed air, natural gas, liquid gases, viscous liquids
· Silencer for pneumatic systems
· Heat exchange
· Condensation of steam
· Evaporation of liquids
· Aeration
· Bulk material compaction
· Pneumatic transport
· Fluidization and fluidized bed
· Tools for thermoforming of plastics
· Tools for polymerisation of plastics (in EPP, EPS)
· Vacuum tables
· Packaging of bulk goods
· Sensor protection
· Vibration protection
· Flame barriers
· Sound absorption
· Decorative application
· Lightweight component
