Alumina Ceramic Foam Filter for Smelting

Product Description

Alumina Ceramic Foam Filter is mainly used for filtration of aluminum and aluminum alloys in foundries and cast houses. Alumina ceramic foam filter is characterised by excellent stability and resistance towards heat shocks. The complexity of filters is not damaged during the casting process. With its excellent resistance to attack and corrosion from molten aluminum, alumina ceramic foam filter 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 steady improvement and development of its filters for molten metal filtration. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. Apply to improve the quality of aluminum alloy and other non-ferrous alloy casting. It can improve metallurgical structure enhance mechanical properties change turbulence into laminar flow porosities. Alumina Ceramic Foam Filters is available in all standard dimensions and different thickness. We provide the whole range of porosities from PPI 10 up to PPI 60 (PPI = pores per inch) or made as per customers' requirements.
