Silicon Carbide 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.

Advantages

1. Low cost.

2. Highest filtration efficiency.

3. Available in 10,20,30 PPI porosity rating.

4. Excellent thermal shock resistance.

5. Suitable for application in C.I, S.G iron, copper alloys etc.
