Product Description

Alumina Casting Alumina Foam Ceramics Filter

Alumina Ceramic Foam Filters mainly for filtration of aluminium and aluminium alloys in foundries and cast houses. With their excellent resistance to attack and corrosion from molten aluminum, they 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. 
Alumina Ceramic Foam Filters(CFF-AL) Common Size: 

CFF-AL is available in all common sizes: 7", 9", 12", 15", 17", 20", and 23". We offers the whole range of porosities from PPI 10 up to PPI 60 (PPI = pores per inch). Custom-made cut-to-size filters are also possible.

Alumina Ceramic Foam Filters (CFF-AL) Gasketing:

CFF-AL is equipped with a gasket on the edges. The gasket assures the proper and tight position of the filter within the filter box. There are different types of gasket available, eg. Ceramic fibre gasket etc. Also you can choose CFF-AL without gasket.
