China Alumina Al2O3 Ceramic Foam Filter for Aluminum Casting

Alumina Ceramic Foam Filter mainly for filtration of aluminium and aluminium alloys in foundries and cast houses. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. Al2O3 ceramic foam filter is just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, SiC Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc. With their excellent resistance to attack and corrosion from molten iron liquid, SIC Ceramic Foam filter 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, all of which contribute to bottom-line profit.
Advantages:
*Filter the surdries in the castings, reduce the casting splracles, reduce the veins flowing when pouring the casting, reduce surface defects, obviously to improve the final-product rate.
*Reduce castings manufacturing duration and the sword and tool damages, improve casting surface manufacturing quality
*Strengthen castings anti-pressure and airproof features, strengthen elongate anti-resistance intensity, to improve surface glabrousness
*Predigest casting system designing requirement, reduce the length of horizontal casting channel, improve castings technology output rate.
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, 15ppi, 20ppi, 25ppi. Higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
