20+ years Focus on Foundry Molten Metal Filtration
NINGXIN Silicon Carbide Sic Alumina Zirconia Ceramic Foam Filter
Sic ceramic foam filter for grey and ductile iron castings filtration
Silicon carbide sic ceramic foam filter of NINGXIN are developed and manufactured for the filtration of cast iron and non ferrous alloys. As the most advanced filter type with the higher filtration efficiency, sic ceramic foam filter can effectively reduce inclusions and turbulence of molten metal, ensuring purified molten metal goes into the mold cavity with improved flow rates.
Using the unique formula and manufacturing process, NINGXIN sic ceramic foam filters have the excellent thermal shock, chemical and high temperature resistance up to 1500°C.
Application:
- Grey iron castings
- Ductile iron castings
- Malleable iron castings
- Non ferrous castings aluminum, copper and bronze alloys
