Alumina Foam Ceramic Filter for Casting

Filtration is an important part of every manufacturing and foundry industry. Different industries use different materials to filter finished products. Alumina foam ceramic filter for casting is used in foundries where molten aluminum is cast. As we all know, aluminum is the best material for many applications, and foundries help mold molten aluminum into different structures to make better use of the metal.

However, unless you use efficient tools to filter it, the process will still be incomplete. The presence of impurities and other harmful products in the metal reduces the quality of the metal, thereby reducing the quality of the material cast from the metal. The ultimate goal of a foundry is to make a profit, and the high quality of casting materials can help achieve this goal.

Alumina ceramic foam filters are mainly used in the filtration of aluminum and aluminum alloys in foundries. Because they have excellent resistance to molten aluminum erosion and corrosion, they can effectively remove inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metals can produce higher-quality castings, fewer scraps and fewer inclusion defects, all of which help increase profits.

Alumina foam ceramic filter for casting has considerable strength at ambient temperature and molten aluminum temperature, sturdy and durable, high thermal conductivity, and chemical corrosion resistance. They can be used in aluminum gravity casting (permanent mold), die casting, low pressure, squeeze casting and high-performance sand casting to remove inclusions.

Alumina ceramic foam filter is characterized by the presence of chemical bonds. The low density and structure of the ceramic frame allow the filter to achieve the smallest dimensional deviation during the production process. From a filtration point of view, the main advantages of the filter include rapid preheating during the casting process and washing the ceramics after casting.
