Our Services
Alumina filter sheet
They exhibit excellent resistance to erosion and corrosion in molten aluminum, and will not chemically react with the molten metal during filtration, thus avoiding secondary contamination.
Silicon carbide filter sheet
Silicon carbide materials have extremely high melting points, allowing them to withstand the scouring and filtration of high-temperature molten metals such as cast iron and cast steel. Their high-temperature strength and chemical stability far exceed those of alumina.
Zirconium oxide filter sheet
It can effectively remove micron-sized non-metallic inclusions (such as oxides and sulfides) from molten steel, significantly reducing the scrap rate of cast steel parts and improving their mechanical properties (strength and toughness).
