Foundrymax D200×30mm / 10PPI Zirconia Ceramic Foam Filter – High‑Performance Filtration for Steel and Superalloy Castings

When casting high‑grade steels and superalloys, the filtration demands are fundamentally different from those of aluminium or cast iron. The melt temperatures are higher, the alloys more aggressive, and the margin for inclusion‑related defects far narrower. Foundrymax’s D200×30mm zirconia ceramic foam filter is engineered specifically for these extreme conditions.

Zirconia (ZrO₂) filters operate reliably at temperatures up to 1700°C. This makes them the material of choice for carbon steel, alloy steel, stainless steel, and high‑temperature alloy applications. 

The 200 mm diameter provides generous filtration surface area suitable for larger steel pours and high‑volume production runs. The 30 mm thickness—significantly thicker than standard 22 mm variants—delivers enhanced mechanical strength to withstand the thermal shock and erosion associated with high‑temperature steel casting. 

Why Foundrymax for This Zirconia Filter?

As a direct manufacturer with full control over sintering and quality inspection, we produce this D200×30 size to order, ensuring consistent dimensional accuracy and material properties. Alternative PPI grades (10, 20, 30) and thickness variations are available upon request to match specific alloy and casting conditions. Our technical team can provide guidance on filter placement and gating design to maximise filtration effectiveness for your specific steel grade and pour weight.
