Its main component is α-alumina (Al₂O₃), with a purity of more than 99%. It has significant advantages such as high hardness, good toughness, strong self-sharpening, uniform particles, good thermal stability, and few impurities. It is widely used in grinding and polishing processes in modern manufacturing.</span>

<span style="font-size: 14pt;">White corundum can be effectively used for surface polishing of metals such as stainless steel, aluminum alloy, titanium alloy, and copper. It has high hardness and strong cutting force, and can quickly remove surface oxide scale, welding spots, oil stains and tiny burrs, making the surface of the workpiece smoother and smoother. At the same time, its particles are pure and it is not easy to produce metal pollution during the polishing process. It is widely used in surface treatment processes in the fields of kitchenware, precision machinery parts, hardware products, metal casings, etc.</span>

<span style="font-size: 14pt;">For brittle non-metallic materials such as glass and ceramics, white corundum has excellent processing adaptability. On the premise of ensuring the integrity of the workpiece structure, white corundum can achieve efficient and uniform removal and polishing, improve the transparency, finish and visual texture of the material, and is suitable for fine surface treatment of architectural glass, ceramic ornaments, crafts and ceramic substrates.</span>

<span style="font-size: 14pt;">In the manufacturing process of high-end products such as precision molds, optical elements, laser devices, etc., there are extremely high requirements for polishing accuracy, surface quality and cleanliness. Micro-powder-grade white corundum (such as F800, F1200, W3.5, etc.) has excellent particle uniformity and cutting stability, and can achieve mirror-level surface effects without causing scratches. It is widely used in terminal polishing in mold manufacturing, optical glass, LED  and other fields.</span>

<span style="font-size: 14pt;">In the processing of electronic materials such as semiconductor wafers, sapphire substrates, and silicon carbide substrates, white corundum has become the preferred abrasive in the polishing process of many electronic components due to its high purity, low impurity content, and low residue. Its stable particle morphology and excellent cutting force help to achieve efficient processing and low defect rate, thereby improving product yield and consistency.</span>
<br class="break/" /><br class="break/" /><span style="font-size: 14pt;"><strong>Summary</strong></span>
<span style="font-size: 14pt;">As a polishing abrasive with stable performance, environmental protection and high efficiency, white corundum plays an important role in metal processing, glass ceramics, precision molds, electronic optics and other fields with its<span style="color: #0000ff;"> <a href="https://www.xinliabrasive.com/products/White-Fused-Alumina" style="color: #0000ff;"><em>high purity</em></a>, <a href="https://www.xinliabrasive.com/products/White-Fused-Alumina" style="color: #0000ff;"><em>high hardness</em></a>,</span> good cutting performance and wide applicability. In the future, with the development of intelligent manufacturing and high-end manufacturing, the requirements for the precision and efficiency of surface treatment will continue to increase, and the application prospects of white corundum will be broader.</span>
