Product Description:
Platelet alumina (the flat shape crystal type aluminum oxide powder for fine abrasives) was produced by special technology, make the powder particle size more homogeneous. The aluminum oxide crystal type is a hexagonal flat shape. Different from the equivalence type or sphericity of tradition abrasive. So the particles will not scratch the workpiece surface. At the same time, because the lapping press distributes equally on the surface of the platelet particles, the number of crashed particles will be less, particles's endurance of lapping will be increased greatly, and so can provide best gri
