The characteristics of liquid metal, influencing on forming of cast porous material, produced by its infiltration through salt particles, are considered in the article. The technological processes of cast porous materials with metal base — aluminium-silicon alloy AK12, providing the obtaining of porosity 60-85 % and pore sizes 0,2-3,0 mm, are given
There are examined the peculiarities of the technology of production cast permeable materials and aluminium articles and alloys using washing out salt filters. There is studied the penetrability of the received materials
