Product Details

Brown corundum sand for resin bond abrasive tools

Brown Fused Alumina is fused and crystallized under the high temperature of above 2250℃ with high quality abrasive bauxite as raw material and matched by the carbon material and scrap iron. It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resinoid grinding wheel, grinding stone,grinding block,sand paper,sand cloth,sand belt,polishing wax,abrasive agent,abrasive paste,coating and so on.
