Brown Fused Alumina

High Temperature Brown Corundum 95% for Vitrified Bonded Abrasives Brown Fused Aluminum Oxide Introduction Brown Fused Alumina(BFA), also called Brown Fused Aluminum Oxide, Brown Aluminum Oxide or Brown Corundum, named by its mainly brown color, is an artificial electro fused corundum obtained from reduced fusion of high quality bauxite together with other raw materials in 2000℃ electric arc furnaces. Bauxite used for producing of BFA contains high Aluminum Oxide(Al2O3).

Brown Fused Aluminum Oxide 95% for Vitrifed Bonded Abrasives Brown Fused Aluminum Oxide Introduction Brown fused aluminum oxide is mainly used as a recyclable abrasive in blast cabinets and blast rooms. Because of its low iron content, alumina is often used in blasting operations where iron contamination on the non-ferrous metal substrate is not allowed. Aluminum oxide is a very hard and sharp abrasive that cleans rapidly. It leaves an anchor profile prior to coating and is

Tilting Furnace Barmac Crushed Brown Fused Alumina for the Shaped and Unshaped Refractories 1. Brown Fused Alumina Descriptions Brown Fused Alumina is made of high-quality bauxite, anthracite, and iron filings. It is cooled and smelted at a high temperature by more than 2000 degrees in an electric arc. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, the sieve is divided into various kinds. Its compact texture, high hardness, suitable for

Tilting Furnace Barmac Crushed Brown Fused Alumina 95% for Coated Abrasives 1. Brown Fused Alumina Descriptions Brown Fused Alumina (BFA) is made by a reduction fusion of high quality bauxites in an electric arc furnaces. It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding. Its thermal properties make it an

High Temperature Calcined Red Brown Fused Alumina 95% for Grinding Abrasives 1. Brown Fused Alumina Descriptions Brown Fused Alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000oC. A slow solidification process follows the fusion, to yield blocky crystals. Strict control over Titania levels during the fusion process ensures optimum toughness of the grains. 2. Brown Fused Alumina Characteristics a. High hardness b
