The hardness of white corundum is remarkable. Its Mohs hardness is around 9, second only to diamond in nature. This makes it show unparalleled power in grinding, cutting and other processing processes. For example, in the automotive manufacturing industry, after the engine block is cast, the inner wall surface is relatively rough and lacks precision. Using a grinding wheel made of white corundum abrasive can quickly grind the inner wall of the cylinder block smooth and meet extremely high precision requirements, ensuring the performance and service life of the engine. In the manufacturing process of metal cutting tools, white corundum can be used for fine grinding of the cutting edge, making the tool sharper and more durable, greatly improving cutting efficiency and quality.
The trays and other utensils made of white corundum can remain stable at high temperatures and provide a reliable foundation for the production of silicon wafers. In the processing of optical elements, the advantages of hardness and purity of white corundum are also fully demonstrated. Its uniformly fine crystal structure and high purity make the processed optical lens have extremely high surface finish and good light transmittance. During the grinding process, no impurities will be introduced to cause flaws in the lens or affect the optical performance, providing a strong guarantee for the manufacture of high-quality optical instruments. For example, in the manufacture of high-end camera lenses, using white corundum for fine grinding and polishing can greatly improve the resolution and imaging quality of the lens.
In addition, as modern manufacturing develops towards high precision and high performance, the requirements for materials are becoming increasingly stringent. Relying on the perfect combination of hardness and purity, white corundum can meet the needs of various precision processing. From the manufacturing of parts in the aerospace field, such as the grinding of aircraft engine blades, to the polishing of electronic chips, white corundum plays a key role.
