Features: The hardness of it is similar to that of whiter aluminum oxide, but its toughness is slightly higher than that of the latter. The edges of its grains are sharp and can be kept well. It is also of high durability.
Application: It is suitable for the grinding of chilled steel, cutting tools and workpieces of alloy steel as well as the precision grinding of measuring tools and parts of instruments and apparatus, etc.
