Ceramic foam filters are primarily used for the filtration of aluminum and aluminum alloys in foundries and cast houses. With exceptional thermal shock resistance and corrosion resistance against molten aluminum, they effectively remove inclusions, reduce trapped gas, and ensure laminar flow. The result is significantly cleaner metal, leading to higher-quality castings, less scrap, and fewer inclusion defects-all of which enhance overall profitability.
