Foundry Filter NALCO uses foam and high-purity ceramics as raw materials to effectively remove the non-metallic solid mixture of aluminum liquid and aluminum alloy flux in the aluminum casting industry.

The ceramic foam filter Al2O3 is specially designed for cast metals. Because of the formation of “filter cake” on one side of the inlet filter, and because of the filtering inside the ceramic matrix.

Alumina ceramic foam filters are mainly used in the purification process of producing aluminum and aluminum alloys. With the continuous improvement of the quality requirements of aluminum products, the application of alumina foam ceramic filters will become more and more extensive.


Ceramic foam filter size:
660x660x50 (26″)
584x584x50 (23″)
432x432x50 (17″)
228x228x50 (9″)
178x178x50 (7″)

Ceramic foam filter pore size (PPI): 10/20/30/40/50/60

Foundry Filter NALCO

Foundry Filter NALCO has an open 3D structure of a ceramic matrix formed by a system of interconnected units. They have good thermal conductivity, stability and resistance to sudden changes in temperature.

Advantages of ceramic foam filter to produce aluminum castings
Uniform pore size, high porosity, perfect sintering, high bending and compressive strength, and good filtering effect.

Aluminium India purchased Filter Foundry through for continuous casting, semi-continuous casting, gravity casting and low pressure casting aluminum flux filtration equipment.
The technical staff of Indian Aluminum Industry believes that the ceramic foam filter is an effective tool to achieve the purity of the molten metal during the casting process. The filter can also stabilize the filling of the mold and prevent unwanted defects in the casting.
