Henan sales corundum

Corundum is high-quality aluminum oxide powder as raw material, refined and crystallized fused, high purity, good self-sharpening, acid corrosion, high temperature, thermal performance and stability it is slightly higher than corundum hardness, toughness slightly lower high purity, good self-sharpening, strong grinding ability, heat a small, high efficiency, acid corrosion, high temperature thermal stability. Made with its abrasive, for grinding high carbon steel, high speed steel and stainless steel fine-grained abrasives can also be used for precision casting and high-grade refractory. Products provide packaging: plastic woven bag 25kg, tons of bags, small bags tons of bags corundum Specifications: of sand: 8-5mm, 5-3mm, 3-1mm, 1-0mm powder: 320-0,280- 0,240-0,200-0,180-0,150-0,120-0,100-0 size sand: F8, F10, F12, F14, F16, F20, F22, F24, F30, F36, F40, F46, F54, F60, F70, F80, F90, F100, F120, F150, F180, F220 powder:.
