1.high hardness,good toughness and sharp shapr in size
2.widely used as refactory materials
Detailed introduction to Brown Fused Alumina Grains F16-220For Abrasives Wheel:
Brown Fused Alumina with high-quality bauxite as raw material, anthracite, iron filings, in the arc melting temperature by more than 2000 degrees made by the plastic from the mill grinding, magnetic separation to iron, screening into a variety of particle size, its texture is dense, high hardness, the formation of spherical particles, for the manufacture of ceramics, resins and high abrasive grinding, polishing, sand blasting, precision casting, etc., can also be used to manufacture advanced refractories. . The level of the main components of corundum corundum is alumina, aluminum content also graded to distinguish between the lower aluminum content will lower the hardness.
