Product Description
Alumina ceramic foam filter:
Ceramic foam filter has the advantages of high prorosity, low loss of thermal shock, high mechanical strength at normal and high temperature, large specific surface, good chemical stability and excellent filtering functions of screen, filtering residum collection and absorption especially for tiny impurity of 1~10um. The three-dimension structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gas and smoothing the casting.
It is not only applied for molten metal filtering in high temperature, but gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry.
With more than ten years of scientific research and development, FCRI has developed a series of ceramic foam filters which are made of different materials such as Aumina, Silicon Carbide and Zirconia.

The steady improvement and development of its filters for molten metal filtration made Patronage. A well-known partner. Alumina Ceramic Foam Filters mainly for filtration of aluminum and aluminum 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. Apply to improve the quality of aluminum alloy and other non-ferrous alloy casting. Improve metallurgical structure Enhance mechanical properties Change turbulence into laminar flow

Alumina Ceramic Foam Filters is available in all standard dimensions and different thickness. We offer 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.

*Decontaminate the melting metal liquid
*Simplified gating system
*Improve the metallurgical structure of the castings
*Reduce imparities of the castings
*Improve casting quality rate
*Reduce casting internal re-oxidation defects
*Reduce the surface defects after machining of the castings

*Increased Fluidity
Removal of inclusions makes the metal more fluid, resulting in easier mold fill, better cast structure, and better thin section castability.
*Reduced Mold and Die Wear
Removal of inclusions and other nonmetallic debris from the melt reduces die soldering and mold-metal interaction, which degrades the mold surface and service life.
*Longer Tool Life
Oxide as well as intermetallic inclusions create "hard spots" that damage tools in machining and finishing operations. Filtration reduces tool wear and increases productivity.
*Fewer Rejects

Inclusions nucleate porosity, create hot tears during solidification, cause surface defects that mar appearance, and often reduce mechanical properties. In many cases, filtration cuts rejects from such causes to virtually zero. Improvements in yield to near 100% and reduced reject rates to at or near 0% are common.
