Alumina Ceramic Foam Filter for molten aluminum filtration
Model Name:NX-PTW-L
Products confirm with China National Standard GB/T 25139-2010.
Application:For the filtration of molten aluminum and non ferrous alloy.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and alloys in foundries and cast houses .With the excellent resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas and provide laminar flow and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.
-Reduce scrap related to inclusions.
-Reduce costs related to inclusion defects.
-Increase productivity with higher extrusion or rolling speeds.
-Increase casting flexibility with easy alloy changes.
-No holding metal.
