Ceramic Foam Filter

Ceramic Foam filters  are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, competitively priced,  foam filter is designed for filtering impurities from liquid metals. 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.

ceramic foam filters are available in four materials:
-Alumina, for use with aluminum and aluminum alloys;
-Zirconia, for use with stainless steels and nickel alloys;
-Silicon carbide, for use with grey iron, ductile iron, precious metals, copper, bronze, brass and investment casting; 

1. CFS(Silicon Carbide Foam Ceramic Filter) for purging Iron casting and cooper casting solutions.
2. (Zirconia Foam Ceramic Filter) for purging steel casting solution.
3. (Alumina Foam Ceramic Filter) for purging aluminium alloy.
4. (Magnesia Foam Ceramic Filter) for purging magnesium alloy;
