Aluminum casting using alumina ceramic foam filter
Alumina Ceramic Foam Filters mainly used for filtration of aluminum and alloys in filter case.
With the excellent corrosion resistance to molten aluminum and strict control of pore size&
porosity, the filter can effectively remove micron impurity and provide stable laminar flow to
realize higher-quality casting. The alumina ceramic foam filter manufactured by our company
has been widely used in purifying system in the founding, low-pressure, semi-continuous,
continuous casting of the liquid aluminum and aluminum alloy.
Characteristics:
