Alumina foam ceramic filter, mainly used in the purification process of aluminum and aluminum alloy production. It can effectively remove all kinds of fineness in the aluminum water to the micron-sized inclusions, make the aluminum water into a smooth laminar flow, which is beneficial to the punching type; has excellent aluminum-resistant water scouring performance, tightly controlled hole size and through-hole ratio A stable filtration effect can be obtained; thereby improving the casting quality, reducing the casting rejection rate, prolonging the service life, and reducing the casting cost.

     Large-size alumina foam ceramic sheets (filter plates) are widely used in aluminum casting workshops such as aluminum alloy cast rods, slabs, aluminum foils, aluminum cans and high-end aluminum profiles. The impurity particle filtration rate of 15 to 20 microns is 98.3%. Help to get the perfect aluminum product. Various specifications can be produced according to customer requirements, the range of 10ppi to 60ppi can be selected, and the maximum size can be up to 23 inches.

    The alumina foam ceramic filter product index meets the national standard GB/T 25139-2010, and has passed the test of the national authority.
