Why brown alumina oxide can be used for sand blasting hard alloy?
High hardness and wear resistance: Brown alumina oxide has a relatively high Mohs hardness 9, which enables it to quickly grind and polish hard alloys and other high-hardness materials. At the same time, it has strong wear resistance, and the particles do not wear easily during the spraying process, allowing for long-term stable cutting performance.
Excellent thermal and chemical stability: brown corundum can maintain its physical and chemical properties stably at high temperatures, making it suitable for processing materials such as high-temperature alloys; its chemical properties are stable, resistant to acid and alkali corrosion, and will not undergo chemical reactions with hard alloys, ensuring the reliability of the processing results.
Sharpness and toughness: Under the action of pressure, the brown alumina oxide particles will continuously fracture to form new sharp cutting edges, avoiding dulling and ensuring rapid cutting during continuous grinding; at the same time, its internal micro-crack structure can absorb impact energy, reducing damage to the workpiece.
Wide applicability: The hardness and toughness of brown corundum are moderate, which can effectively remove the oxide layer, burrs and scratches on the surface of hard alloys, while achieving smooth processing and improving processing efficiency.
