White Fused Corundum

White Fused Corundum HS Code 28181090, CAS No. 1344-28-1. White Fused Corundum has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory. It can also be used as sandblasting, lapping and polishing medium, precision founding sand, coating materials, catalyst carrierand special ceramics


White Fused Corundum segmental sand
It is particle size range of 0-1mm, 1-3mm, 3-5mm, 5-8mm, 100#-0, 200#-0, 320#-0, etc.  It is mainly used as shaped refractory material, unshaped refractory material and flooring sand.

White Fused Corundum fine powder
It belongs to White Fused Corundum section sand, the product of 0 to a certain particle size in section sand is also called fine powder, it is the product that passes the finest sieve in White Fused Corundum section sand production line, the general models are: 100#-0, 200#-0, 320#-0, 0-1mm.

White Fused Corundum particle size sand
Also called White Fused Corundum number sand, is mainly divided into White Fused Corundum F sand and White Fused Corundum P sand and national standard micronized powder W number.

White Fused Corundum micro powder
White Fused Corundum micronized powder is selected from high quality White Fused Corundum fine powder in White Fused Corundum section sand production line, further crushed and shaped by tube mill, magnetic separation to remove iron, acid washing and moisture.
