Alumina Foam Ceramic Filters for Cast Aluminum
2022-09-20

Alumina foam ceramic filters are mainly used in the purification process of aluminum and aluminum alloy production. They can effectively remove all kinds of inclusions with a fineness of microns in the aluminum liquid, so that the molten aluminum becomes a stable laminar flow. They are beneficial to the flushing. Alumina ceramic foam filter has excellent resistance to aluminum liquid erosion, and strictly controls the pore size to obtain stable filtering effects. It improves the casting quality, reduces the scrap rate of castings, prolongs the service life, and reduces the casting cost.

Large-sized alumina foam ceramic filter plates are widely used in aluminum melting and casting workshops to get the perfect aluminum product. Such as aluminum alloy casting rods, flat ingots, aluminum foils, aluminum cans, and high-end aluminum profiles.
