Zirconia Ceramic Foam Filters are used for molten all types of steel like unalloyed, low alloyed, stainless, and high-alloyed as well as Nickel and Cobalt-based super-alloys. With their excellent resistance to attack and corrosion from molten steel 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.
