Description
FILTEX® AL Ceramic Foam Filters , These filters are used for pouring of Aluminium alloys into chills and into sand moulds , Alumina Ceramic Foam Filters are mainly used for filtration of aluminium and alloys in foundries and cast houses. With the excellent resistance to attack and corrosion from molten aluminium, the filter can effectively remove 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.
