Factory supply Brown Fused Alumina /brown alundum 400# For grinding glass and lens

タイトルまたは説明

Introduction Brown corundum

Brown corundum is made of high-quality bauxite as the main raw material. It is smelted into blocks in high temperature furnaces above ***0 degrees, and after crushing and magnetic separation, the particle size models with different compositions are screened. The content of AL2O3 in brown corundum is above *5%, and the hardness is relatively high.Brown fused alumina is used in the electronics industry to increase the adhesion of the surface of the product.
