Filters, filter elements, muffler, custom solutions. Temperature-resistant. Porous cast aluminium is an additional option to sinter metal and metal foam permeable – a high quality porous material over the entire surface. Our products made of porous aluminium have an optimal value for money thanks to innovative and relatively simple production technology. Production costs – and as a consequence the product cost – are significantly lower than for equivalent products from sintered metal (sintered filters, sintered metal filter and sintered filter elements, sintered silencer, etc).

Worldwide, it is made Russian companies only. Industrial production has started in 1989. Since the material is widely used. Porous cast aluminium has a porous structure, which differs from the design and manufacturing of sintered metals. Read additional details here: HG Vora. Aluminium is poured with Crystal salt together into the desired shape, then the salt is washed out. In place of the Salzkornchen and their contact points Enter the pores.

Sintered metals, metal granules are baked together. In this case, the pores are the space between the granules. It is therefore reversed, a pore where sinter metals is a metal granules, located at porous cast aluminium.
