Alumina Ceramic Foam Filters are an essential element in the metal casting process, such as aluminum and aluminum alloy. They eliminate impurities and ensure that only high-quality molten metal is poured into the casting mold.
Alumina ceramic foam filter is made of high-quality alumina ceramic material and has a unique structure that allows for efficient aluminum liquid.
SEFU alumina ceramic foam filters are widely used in the foundry industry for molten metal filtration, such as aluminum and aluminum alloy castings.
They are designed to remove impurities such as slag, sand, and metal oxides from the melt. Our filters are known for their exceptional flow rate capacity, fine particle retention, and excellent thermal shock resistance.
