white fused alumina

white fused alumina for sand blasting 1) size :16-320mesh 2)packge:25kg/bag

white fused alumina for sand blasting With high-quality aluminum oxide powder as raw material, white corundum is formed by the fused smelting. It has the white color, high hardness, toughness, high purity, high efficiency, acid and alkali corrosion, good thermal stability characteristics and many other characteristics. It is not only advanced abrasives materials, but also advanced grinding, polishing materials. It is suitable for grinding hardened alloy steel, high speed steel.  Fine-grained flour is also used for precision casting.Our company exports white corundum products perennially to Japan, Korea, Europe and the United States and other countries and regions. We can offer you all types of white corundum products, such as F sand, P sand, powder and so on.
