foam filters are available in four materials:
Silicon carbide, for use with grey iron, ductile iron, precious metals, copper, bronze, brass and investment casting; And
Magnesia, for use with magnesium alloy.
All of the materials are available in square, round and custom geometric shapes; Sizes ranging from 10mm up to 600mm; And thicknesses from 10-50mm. Pore densities from 8-40 pores per inch are available.
Technical Data:
Bore Density(PPi)/PP 4-60
Porosity (%) 80-90
Refractoriness 1100-1500
Bending Strength (Mpa) 0.8
Compression Strength (Mpa) 0.9
Thermal Shock Resistance 6
Packing:Packed in cartons
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.
As per the baove, if you have any question , PLS let me know , we will try my best to do it .
best regards
