Silicon Carbide (SiC) Ceramic Foam Filters


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.
