Alumina Ceramic Foam Filters are mainly used for filtration of aluminium and alloys in foundry and cast house. With the excellent attack and corrosion resistance of molten aluminum, the filter can effectively remove inclusions, reduce trapped gases and provide laminar flow, so the filtered metal is significantly cleaner. Cleaner metal results in better quality castings, less scrap and fewer embedding defects, all of which contribute to the bottom line.
Aluminium foundry ceramic foam filters adopt unique technology and raw material. Heat resistance, filtration efficiency and resistance parameters are all beyond standard requirements. With highly innovative ability and years of cooperation with scientific research institutes, the foundry ceramic foam filter is in line with the development of foundry industry, and can greatly help users to improve the quality of castings and to lower the costs.
Besides the general specifications, Adtech can offer the product according to customers’ requirements. Uniform opening, high porosity, proper sintering, high resistance to anti-bending and anti-compression, efficient filtering. It is widely applied to aluminum fusion filter equipment of continuous casting, semi-continuous casting, gravity casting, and low pressure casting.
Specifications of Aluminum Foundry Ceramic Foam Filters

Ceramic foam filters are basically divided into 10PPI, 20PPI, 30PPI, 40PPI, 50PPI and 60PPI. The larger the number, the smaller the aperture. But in actual practice, the four types of 10PPI 20PPI 30PP 40PPI can meet the needs of customers. 30ppi 40ppi Foundry Filter is the most commonly used ceramic foam filter in the aluminum casting industry. Ordinary aluminum casting usually uses 10-40ppi ceramic filter plates. Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.
