Fused Zirconia Alumina
Zirconium corundum is made of high-purity alumina and zirconium material as raw materials. After high temperature smelting at 2250℃, it is formed by special processing technology and Barmac ball milling. It has high quality, extremely hard, compact structure and special crystals, dendritic eutectic structure. According to the content of ZrO2, zirconium corundum can be divided into ZA25 zirconium corundum (ZrO225%) and ZA40 zirconium corundum (ZrO2 40%).
The biggest feature of zirconium corundum that is different from ordinary corundum and silicon carbide is superior self-sharpening, toughness and wear resistance. Used for making grinding wheels, it can significantly improve the life and sharpness of grinding wheels, and for grinding and cutting workpieces with higher hardness, the wear resistance is particularly obvious. Mainly used in the production of heavy-duty grinding wheels, resin grinding wheels, cutting discs, wear-resistant products, high-end abrasive tools, etc., suitable for steel parts, cast iron parts, heat-resistant steel, titanium alloys, nickel alloys, aluminum alloys, tungsten titanium alloys and other materials The grinding force is higher than that of ordinary corundum products.
Characteristic:
Application:
Used to produce heavy-duty grinding wheels, barren grinding wheels, rail snagging & grinding wheel, cutting disc, and high-grade resin bonded grinding wheels.
Abrasive Disc for grinding and cutting difficult to grind materials.
Raw material for high-end production of cutting discs, grinding discs, polishing wheels, etc.
Used to produce coated abrasives, such as sandpaper, abrasive belts, flexible polishing wheels, etc., to improve polishing accuracy and work efficiency.
