- Information
Zirconia Casting Ceramic Foam Filter
Zirconia ceramic foam filters exhibit excellent resistance to sudden thermal shock, with a typical tolerance of up to 1700°C. Made from a durable composite material called Zirconia, they are featured in yellow and known for withstanding high pressure without warping or breaking down.

Features
• Dimensional precision makes the zirconia ceramic filter easy to integrate into casting systems, minimizing the need for manual adjustments during installation.
• Lightweight construction defines the zirconia ceramic filter, facilitating easier handling and setup.
• Zirconia ceramic filters can be flexibly positioned to adapt to different metal flow directions and mold designs.
• Corrosion resistance is a key advantage of the zirconia ceramic filter, ensuring durability in demanding casting environments.

Application
• High-strength alloys such as engine parts and structural components is the ZrO₂ foam ceramic filter.
• Commonly used in pumps, valves, and fittings made from corrosion-resistant stainless steel is the ZrO₂ foam ceramic filter.
• ZrO₂ ceramic foam filters are used for precision-molded stainless steel-automotive parts.
• The ZrO2 foam ceramic filters made by us are often used in nickel-based and cobalt-based alloy castings.
