Alumina Ceramic Foam Filters mainly for filtration of aluminium and aluminium alloys in foundries and cast houses.
Alumina Ceramic Foam Filter:
Ceramic foam filter is mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses.
With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas 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.
