Brown corundum sand
The physical and chemical properties
Brown corundum sand has shell fracture and sharp edge, which can form new edges and edges in continuous grinding and grading, making its grinding ability better than other abrades. In particular, it has the advantages of high hardness, large ratio, stable chemical properties and its unique self-sharpening become the first choice for abrasive blasting process; At the same time is sandblasting rust cleaning workpiece, grinding and polishing of the ideal material.
