Brown aluminum oxide is electrically fused in an arc furnace from a mixture of bauxite at high temperature. It has brown color, high hardness and great toughness. The abrasive tools made of brown aluminum oxide are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze.It used for refractory aluminum oxide lining mixture, pouring materials castable,etc.
Applications
1.For Free grinding, such as glass industry.
2.For Friction products and abrasion resistance ground
3.For Resin or ceramic bonded abrasive,such as grinding wheels,cutting off wheels.
4.For Refractory Raw material, Wear-resistant and fire-proof products.
5.For Grinding and polishing ,such as gringing stone, Grinding block, flap disc.
6.For Coated abrasives,such as abrasive paper,abrasive cloth,abrasive belt.
7.For Producing mold of precision casting and Grinding, lapping and polishing media
