Ceramic foam filter is just developed as a new type of molten metal filters to decrease casting flaw in recent years. It is made from high quality ceramic materials, whose main components are Al2O3, Sic, ZrO2, MgO etc. Ceramic Foam Filter has the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal. With the distributing pores net structure, they are able to increase the surface areas, and absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less and the cast quality becomes much better.
We can supply ceramic foam filters are as follows:
*Silicon Carbide Ceramic Foam Filter is applied to purge and filter solution of ductile iron casting, grey iron and other iron casting.
*Zirconia Ceramic Foam Filter is applied to purge and filter solution of steel high temperature metal such as steel alloy stainless steel etc.
*Magnesia Ceramic Foam Filter is applied to purge and filter solution of magnesium and magnesium alloy.
*Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and aluminium alloys.
