Manufacturing technology of porous aluminium

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.

Manufacturing technology of porous aluminium:

– Aluminium is casted together with salt (NaCl)

– Mechanical post-processing

– Salt washing out

For the manufacturing of porous aluminium we use salt crystals with different sizes. In that way products with different pore sizes will be obtained.  For more information regarding the material properties please click here.

For the manufacturing of porous aluminium we do not use any cost-intensive pressing moulds as sinter technology needs, but conventional casting moulds. Our products made of porous aluminium have – thanks to innovative and relative simple manufacturing technology – an excellent quality-price ratio.

The relatively simple casting process is followed by the mechanical finishing. Thus we get products with a broad range of all possible designs, shapes and sizes.
