Cff-s is a range of new generation silicon carbide based ceramic foam filters with a consistent, high level performance in terms of metal flow rate and filtration efficiency. Cff-s filters are intended for filtering grey, ductile iron and nonferrous metals at the temperatures up to 1450 â°c. The filters can be placed in the gating system of the mould as well as in combination with exothermic extensions for direct casting/pouring on the filter. They can also be used for continuous non ferrous metal filtering, e.G. Production of copper wires, roads.
Features:
1. High strength
2. Excellent corrosion resistance
3. Outstanding thermal shock resistance
4. Available in kinds of shapes, in a variety of pore sizes, e.G.10ppi, 20ppi, etc.
Functions:
1. Clean iron castings
2. Fewer inclusions
3. Increased casting yield
4. Cost-savings from reduction in scrap
5. Lower costs for machining of the castings
