Product Description
Alumina Ceramic Foam Filter
Alumina ceramic foam filter is a new type of low-density, high-porosity filter with a three-dimensional network skeleton structure. It is widely used in the aluminum process industry for molten aluminum filtering, improving aluminum quality.
Alumina ceramic foam filters can effectively remove non-metal solid mixture from aluminum and aluminum alloy fusion, reduce trapped gas, and provide laminar flow. Then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects. It improves the quality of aluminum alloy and other non-ferrous alloy castings, all of which contribute to reducing casting cost, its maximum service temperature of 1200°C.
Product Application
It is mainly used for the purification process of aluminum, aluminum alloy, and other nonferrous alloy production.
Alumina ceramic foam filter is mainly applied to the aluminum and aluminum alloy fusion filter equipment of continuous casting, half-continuous casting, gravity casting, and low-pressure casting, and also applied to other non-ferrous metal precision casting.

Detailed Photos
The 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 gaskets available, e.g. ceramic fiber gaskets, etc., which also can provide alumina ceramic foam filters without gaskets. These types of filters have been favored by customers from Europe and the United States for years.
