Aluminium Scrap Metal Foam Filter can reduce the turbulence of the molten aluminum and purify the molten aluminum.
The filtered and purified aluminum castings can significantly extend the service life of parts with high demand such as aviation and auto parts, and also have good effects on aluminum and copper parts that require surface polishing.
Foam ceramic filters also play an important role in the traditional aluminum industry, electrical aluminum industry and continuous casting and rolling processes.
Because aluminum and its alloys have a large specific gravity and produce large thermal shocks during casting, the alumina foam ceramic filter used in the aluminum casting process generally has strict regulations on the size.

In aluminum casting production, the casting reject rate caused by casting defects such as non-metallic inclusions generally reaches 50% ~ 60% of the reject rate.
Inclusion defects not only severely reduce the mechanical properties of the casting, but also have a harmful effect on the processing performance and appearance of the casting.
Purifying liquid casting alloys and reducing or eliminating various non-metallic inclusions are undoubtedly important technical measures to obtain high-quality castings.
Since the successful development of the aluminum alloy foam ceramic filter in 1978, the foam ceramic filter technology has developed rapidly. The use of ceramic foam filter technology can effectively achieve the purpose of purifying molten aluminum alloy.

Aluminium Scrap Metal Foam Filter

Alumina has excellent strength and resistance to high temperature impact and chemical corrosion.
Therefore, it is suitable for the casting of all aluminum alloys.
The alumina ceramic foam filter can significantly improve the quality of cast aluminum parts and reduce the rejection rate.
Alumina ceramic foam filters can also be used in continuous casting and continuous rolling processes, and can be manufactured into various standard sizes and different thicknesses.

Ceramic foam filter Pore Size (PPI): 10/20/30/40/50/60

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.
