Product Description

Alumina ceramic foam filter is a new type of low density, high porosity and with three dimensional network skeleton structure of the filter. And widely used in aluminum process industry for molten aluminum filtering, so as to improve aluminum quality. Alumina ceramic foam filter can effectively removes non-metal solid mixture from aluminium and aluminium alloy fusant, 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, to improve the quality of aluminum alloy and other non-ferrous alloy casting,all of which contribute to reduce casting cost, its maximum service temperature 1200° C.

Alumina ceramic foam filter 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,e.g. ceramic fiber gasket etc., also can provide alumina ceramic foam filter without gasket. These types of filters have been favored by customers from Europe and the United States for years.


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.

Our Advantages

Alumina ceramic foam filter has the advantages of high porosity, high mechanical strength, stable chemical property, strong corrosion-resistant, high adsorption rate, excellent filtering functions and thermal shock resistance. It is mainly used for purification process of aluminum, aluminum alloy, and other nonferrous alloy production, can also be used as gas-solid, liquid-solid separation medium, catalyst carrier, burner and sound-absorbing and environmental protection fields.

Product Features

1.Structure: three-dimensional network structure, smooth rectification and filling The upper, middle and lower three-dimensional network has no blocked holes, no blind holes, reducing eddy current, flocculation laminar flow, and stable filling

2.Filtration: Labyrinth channel, efficient mechanical slag blocking There are microscopic gaps, strong adsorption of slag, effective filtration, oxide inclusions, slag and other large impurities

3.Performance: Large internal specific surface area of the filter The grout is sufficient and without blind holes, forming a complete multidimensional, three-dimensional channel of pore reinforcement, absorbing micro-inclusions
