Diameter 100 x 25 mm – 10 PPI Zirconia Ceramic Foam Filters for Steel Casting

Foundrymax – Round Ø100×25mm / 10PPI Zirconia Ceramic Foam Filter for Steel Casting

• Material: Zirconia (ZrO₂), max service temperature 1700°C

• Pore Density: 10 PPI – maintains high flow rates for steel alloys

• Dimensions: 100 mm diameter × 25 mm thickness (round disc)

• Structure: Open‑cell reticulated foam

• Core Functions: Removes non‑metallic inclusions, oxides, slag, and refractory fragments from molten steel; reduces turbulence and gas entrapment

• Primary Applications: Carbon steel, alloy steel, stainless steel, and high‑temperature alloys – suitable for medium‑sized steel castings and investment casting

Foundrymax Round Ø100×25mm / 10PPI Zirconia Ceramic Foam Filter – High‑Temperature Filtration for Steel Foundries

Steel casting places exceptional demands on filtration media. Pouring temperatures typically range from 1550°C to 1650°C, Foundrymax’s Ø100×25mm zirconia ceramic foam filter is engineered specifically for these conditions, delivering dependable performance at temperatures up to 1700°C across carbon steel, alloy steel, and stainless grades.

Purpose‑Built Format for Medium‑Sized Steel Castings

The 100mm diameter round format is a practical choice for many steel foundry applications—sufficiently large for high‑volume pours, yet compact enough to fit neatly into round sprue wells or pouring cups. The 25mm thickness provides enhanced mechanical strength over standard 22mm variants, reducing the risk of fracture during handling and withstanding the thermal shock of molten steel contact. 

Why Foundrymax for This Zirconia Filter?

As a direct manufacturer with expertise in zirconia processing, we produce this Ø100×25 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.
