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: 1. Silicon Carbide Ceramic Foam Filter is applied to purge and filter solution of ductile iron
casting, grey iron and other iron casting. 2. Zirconia Ceramic Foam Filter is applied to purge and filter solution of steel high temperature
metal such as steel alloy stainless steel etc. 3. Magnesia Ceramic Foam Filter is applied to purge and filter solution of magnesium and
magnesium alloy. 4. Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and
aluminium alloys.
