Product Description
Add: Guanting Industrial Park, Cangzhou City, Hebei, China
Alumina Ceramic Foam Filter (CFF)
Alumina ceramic foam filters can effectively remove the non-metal solid mixture from aluminum and aluminum alloy fusant, reduce trapped gas, and provide laminar flow. Then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects. It improves the quality of aluminum alloy and other non-ferrous alloy castings, all of which contribute to reducing casting cost, its maximum service temperature of 1200°C.
Alumina CFF Features
1. Superior dimensional tolerances.
2. Stable chemical property.
3. Excellent filtration efficiency.
4. Excellent mechanical strength.
5. Resistant to corrosion and thermal shock resistance.
6. Beveled edges and compressible gasket.
Product Application
Alumina ceramic foam filter is mainly applied to the aluminum and aluminum alloy fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low-pressure casting, also applied to other non-ferrous metal precision casting, gas-solid and liquid-solid separation medium, high-temperature gas filter, chemical filling, sound absorbing material and catalysis carrier, etc.
