OA60

Yellow and single-crystal particles, is an integral hexoctahedron, with super transparency, high hydrostatic pressure and mechanism pressure, with super hardness, strong impact resistance and thermal stability. It applies for cutters, drill bits, metal bond tools and electroplated tools,etc.

OA40

Yellow and single-crystal particles, is an integral hexoctahedron, with excellent transparency, a little impurity and high strength. It suits for high-load grinding and polishing, such as industry glasses, ceramics and stones etc.

OA30-

Yellow and regular particle shape, with medium impact and thermal stability and resistance .It applies for grinding tools with middle-low load, etc.

OA30

Yellow and single-crystal particles, is an integral hexoctahedron ,with good transparency and high strength . In some place it can replace OA40 , price value. It suits for grinding tools, drillings, industry ceramics, etc.

OA20

Yellow and single-crystal particles, the shape is irregular has good transparency, with low hydrostatic pressure and mechanism pressure. It applies for grinding non-metallic-crisp, magnetic materials, jade and jewels etc.

OA15

Yellow and angular crystal particles, some has a dot inner, rough surface, low impact. It suits for polishing low load tools, such as ceramics, jades, grinding block etc.

OA10

Yellow and irregular particle shape, rough surface, It applies for resin bond tools, ceramic bond tools, grinding carbide and magnetic materials etc.
