Semi-friable aluminum oxide is a kind of high-grade corundum synthesized by some advantages of brown corundum
and white corundum. Its friability is between white corundum and brown corundum. Its grinding performance is unique, and its application range is wide. Semi-friable aluminum oxide has good toughness and self-sharpening. It can be used in the manufacture of ceramic grinding tools, resin grinding tools and coated abrasives. The bonded abrasive tools with semi-friable aluminum oxide have high durability, good self sharpening and retention. Under the same conditions, the surface quality, the processing efficiency and the durability of the grinding tools which produced from semi-friable corundum
are better than those of brown, white, chromium and single crystal corundum when processing some workpieces. For rough grinding, the machining efficiency can be improved, and the surface quality of the workpiece can be improved by fine grinding.
