Foundrymax Square Type 50×50×22mm / 10PPI 20PPI Silicon Carbide Foam Ceramic Filter – Engineered for High‑Performance Molten Metal Filtration
Foundrymax offers a premium‑grade Square Type 50×50×22mm 20PPI Silicon Carbide (SiC) Foam Ceramic Filter, specifically designed for the filtration of molten iron (gray iron and ductile iron), as well as aluminum and copper alloys. This filter features a three‑dimensional reticulated structure with over 85% open porosity, ensuring excellent flow permeability while efficiently capturing inclusions.
With a 20 PPI (pores per inch) density, this makes it ideal for medium‑to‑small precision castings where surface finish and internal integrity are critical. The maximum working temperature reaches 1500°C, making it reliable for most ferrous and non‑ferrous casting processes.
Key benefits include:
-
Effective removal of slag, dross, sand inclusions, and gas bubbles – significantly reducing scrap rates.
-
Improved casting density and mechanical properties due to cleaner melt.
-
Consistent pore distribution ensuring uniform filtration across the entire surface.
-
Excellent thermal shock resistance and chemical stability against molten metal erosion.
