Baoding Ningxin New Material Co.,Ltd.

Model Name:NX-ECF
Extruded ceramic filters for foundry molten metal filtration
Application: Grey iron, ductile iron, aluminum alloy and other non-ferrous alloys.

NX-ECF filter can effectively remove inclusions and eliminate turbulence in the metal stream. Mullite-based ceramic material with a dense network of perfectly cells to withstand thermal shock and extreme pouring temperatures. The cellular design also provides an engineered balance between flow rate and strength. Our extruded ceramic filters have excellent properties of good thermal stability, high specific surface area and resistance to acid and alkali. They are applicable to wide and extensive foundry filtration applications and processes.

Product features
-Decrease the impurity of molten metal
-Deduce the turbulence of molten metal
-Improve the castings mechanical properties
-Decrease machining cost and improve the cutting characteristics
-Improve casting quality and yield
