Buy high quality low price Alumina Ceramic Foam Filter for filtering molten aluminum and aluminum alloys to remove oxides from the surface of aluminum and thus increase casting quality.
 
Alumina Ceramic Foam Filter (ACFF) is a specialized filter made primarily from aluminum oxide (Al₂O₃). It is widely used in metallurgical industries, especially for filtering molten aluminum and aluminum alloys during casting processes.
 
What is an Alumina Ceramic Foam Filter?
Material: Made from alumina (Al₂O₃) with high thermal and chemical stability.
Structure: Open-cell foam with porous, sponge-like structure.
Porosity: Typically available in various PPI (pores per inch) – like 10, 20, 30, 40 PPI.
 
​​​​Applications
Aluminum Casting Industry: Removes inclusions (oxides, slag, and other impurities) from molten aluminum.
Improves quality: Enhances surface finish and mechanical properties of castings.
Automotive & Aerospace: Used for high-performance castings that require high purity.
 
Key Benefits
Excellent thermal shock resistance
High filtration efficiency
Improves casting reliability
Resistant to corrosive attack from molten metals
 
How It Works
The molten metal flows through the filter's porous structure:
Traps inclusions on the surface and inside the filter.
Smooths flow of molten metal into the mold.
Reduces turbulence, minimizing defects.
 
Advantages :
Reduce surface defects in castings
Prevent inclusion of gas and impurities in molten metal
Stable flow of the molten metal
Reduce tool abrasion
Possess high mechanical strength
Highly resistant to thermal shocks
Easy placement in the production line
