Single crystal corundum (also known as SA) is selected from Ruishi Company's alumina powder as the main raw material. Each particle size product is produced by natural crystallization, not the result of mechanical crushing. Because the particles are composed of a single crystal, it has the advantages of good polygonal cutting edges, high hardness and toughness, strong grinding ability, and low heat generation.
Is a very good heat-resistant high-grade abrasive material, used to make advanced cutting and grinding tools, suitable for grinding high-hardness, high-toughness materials such as high-vanadium high-speed steel, austenitic stainless steel, heat-resistant alloy steel, titanium alloy , Especially suitable for dry grinding and grinding of deformable and burnt workpieces.
