High quality raw materials


Metal processing

Brown fused alumina abrasive can be used for grinding, polishing, and finishing of metals, such as steel, cast iron, aluminum alloys, etc. In the metal processing process, it can remove surface oxide scale, scratches, and burrs, improve the quality and smoothness of the metal surface, and provide a good foundation for subsequent treatment.


Ceramic manufacturing

Brown fused alumina abrasive is used in ceramic manufacturing to grind and polish ceramic products, such as ceramic tiles and ceramic bathroom equipment. It can remove defects and burrs on the surface of ceramics, improve the smoothness and appearance quality of ceramic products.


Precision machining

In the field of precision machining, Brown fused alumina abrasives can be used for processing and polishing precision components. Due to its high hardness, high-precision machining of precision components can be achieved, improving the dimensional accuracy and surface quality of the parts.


Grinding tool manufacturing

Brown corundum abrasive can also be used for the production of grinding tools, such as grinding wheels, abrasive belts, etc. It can provide high cutting force and grinding effect, making the grinding process more efficient and accurate.
