Abrasives Powder Brown Fused Alumina

Model Number: Abrasive-#8992 Brand Name: Baiyun Key Specifications/Special Features: Process of productionBrown fused alumina is produced from bauxite, charcoal, iron chip by being fused under high temperature in an electric arc furnace. It is characterized by high toughness and has a micro hardness of 2000-2200kg/mm. The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze, and more. Brown fused alumina can also be used for making fine quality refractory and moreApplicationBrown fused alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening Items Unit Index Typical Chemical
