Brown Fused Alumina For Abrasive
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.
