The basic materials of the ceramic foam filter are three kinds of silicon carbide, zirconium oxide and aluminum oxide.

The basic material of the zirconia foam ceramic filter is zirconia ZrO2. The zirconia filter has a heat resistance temperature higher than about 1760 ° C and has a very high strength and an excellent high temperature impact force.

Cast steel parts are widely used in applications that require high strength and elongation requirements. Therefore, steel castings are very sensitive to defects caused by impurities. The excellent characteristics of the zirconia foam ceramic filter can effectively remove the impurities that ultimately lead to product quality defects. The impurities are mainly composed of non-metal particles, slag, and refractory fragments, which improve the surface quality and mechanical properties of the casting and reduce the scrap rate.
 

Characteristics of silicon carbide foam ceramic filter:

Silicon carbide has excellent strength and high temperature impact resistance and chemical corrosion. It can withstand high temperatures up to about 1560 °C. They are therefore suitable for the casting of all copper alloys and cast iron. The ceramic foam filter can significantly improve the quality of cast iron parts and reduce the scrap rate. It can also be used in the continuous casting and rolling process, and can be manufactured to all standard sizes and different thicknesses.

Silicon Carbide Ceramic Foam Filters mainly for filtration of cast iron and non-ferrous alloys. With their excellent resistance to attack and corrosion from molten iron liquid, they can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

SiC Ceramic Foam Filters (CFF-SC) is available in all standard dimensions and different thickness. The most common porosities are PPI 10, 20 and 30; higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
