Foundrymax Square 75×75×25mm / 10PPI Zirconia Ceramic Foam Filter – Engineered for Steel Casting Performance

When casting carbon steels, alloy steels, or stainless grades, the thermal demands exceed what silicon carbide filters can reliably handle. Foundrymax’s 75×75×25mm zirconia ceramic foam filter offers the elevated temperature capability and erosion resistance required for these demanding applications, maintaining structural integrity at operating temperatures up to 1700°C.

For steel—where pouring temperatures typically range from 1550°C to 1650°C—zirconia (ZrO₂) is the appropriate choice. It withstands both the higher thermal load and the chemically aggressive nature of steel slags, without softening, cracking, or introducing contamination. 

Why Foundrymax for This Zirconia Filter?

As a direct manufacturer with expertise in zirconia processing, we produce this 75×75×25 size with strict quality control over sintering parameters and dimensional accuracy. Alternative PPI grades (10, 20, 30) and thickness variations are available upon request to match specific alloy and casting conditions. Our technical team can advise on filter positioning and gating design to maximise performance for your steel grade and section thickness.
