Brown fused alumina can be used for sand blasting?
Brown fused alumina with high quality bauxite, iron filings, anthracite in the arc of high temperature smelting, grinding and shaping, magnetic separation of iron, screening into a variety of particle size, the main chemical composition is AL2O3, its content in 94% -96%, the other contains a small amount of Fe, Si, Ti and so on. Its dense texture, high hardness, brown, toughness, suitable for manufacturing ceramics, resin high consolidation abrasive and grinding, polishing, sandblasting, precision casting, refractory materials and so on.
The Mohs hardness of brown corundum is 9, and the Al2O3 content is more than 95%, which is a very high hardness artificial abrasive. Widely used in sandblasting, polishing and other surface treatment processes. Using brown corundum to sandblast the workpiece surface has good effect and high efficiency.
