Silicon Carbide Foam

Silicon Carbide Foam Description

Silicon Carbide Foam is an advanced ceramic material ideal for high-temperature filtration applications, particularly in the casting of ductile iron, gray iron, and copper-based alloys. It offers outstanding thermal shock resistance, mechanical strength, and chemical stability, allowing it to perform reliably in extreme molten metal environments. The open-cell structure enables effective removal of inclusions and impurities, while also reducing turbulence and gas content during pouring. This contributes to improved surface finish, structural integrity, and overall quality of cast components.
