Alumina Ceramic Foam Filter
Alumina Ceramic Foam Filters mainly for filtration of aluminum and aluminum alloys in foundries and cast houses. With their excellent resistance to attack and corrosion from molten aluminum, they can effectively remove inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly clearner. Clearner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.
The size are available in square, round and custom geometric shapes; sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 20ppi, 30ppi, 40ppi. The big alumina foam filter are available in size: 7’,9’,12’,15’,17’,20’,23’.
