Product Description F36 sand blasting aluminium oxide / brown fused alumina / BFABrown Fused Alumina is also called Brown Corundum, it is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials.What Is Difference Between Tilting Furnace Melted BFA & Fixing Furnace Melted BFA ?Ball Milling & Barmac Process?1. Tilting furnace process affects SiO2, SiO2 <1% by Tilting furnace, SiO2 <1.5% is by fixed furnace.2. Barmac affects the density, the grain shape is rounder & the density is greater than ball milling3. The Tilting furnace made BFA has high Al2O3 content4. The corundum has good toughness & more suitable for abrasive products by dumping furnace process The difference between F-grit & P-grit Abrasive grains:F-grit is more suitable for bonded abrasive tools.P-grit is more suitable for coated abrasive tools. It is with a closer tolerance size distribution, lower density, and better self-sharpening ability than non-P-grit abrasives, which means that they offer a more consistent surface finish.
