Zirconia Foam Filters

These filters are made by replication technique using high quality recticulated foam imported from Germany (Europe).
These filters provide very high surface area made up of the materials like Sic, Zirconia, Alumina, Etc. which are non wetting to metals and wetting to the metal oxides and other non-metallic materials.
The tortuous path for liquid metal in the structure of the filter controls the speed of liquid metal and the metal gets sufficient time in contact with the filter surface area which increases the filtration efficiency.
The metal leaving the filter flows perfectly in a laminar fashion & further oxidation of liquid metal is fully controlled before its entry into the mould.


1. These filters are suitable for filtration of all types of steel alloys where pouring Temp does not exceed 1650C°

2. They can be used for filtration of C.I / S.G Iron in case of large casting pouring.

3. Available in standard sizes of configurations.

4. Custom sizes can be made on request.
