SG abrasives have broad application prospects and market demand will continue to grow

SG abrasives, also known as ceramic microcrystalline corundum, are currently the most advanced abrasives in the corundum system. They refer to corundum abrasives produced using the sol-gel process, with microscopic grain sizes of 50-500 nanometers. SG abrasives are available in blue and white appearance, and the particle shapes include natural particles, round bars, triangular bars, triangular flakes, etc. The main component of SG abrasives is ɑ alumina. As a new generation of alumina abrasives, SG abrasives have the advantages of high hardness, good toughness, high grinding efficiency, strong sharpness, and good self-sharpening properties.

In industry, SG abrasives are often used to make various types of bonded and coated abrasives, suitable for grinding aerospace alloys, quenched workpieces, tool steel, hard cast iron, bearings, heat-resistant alloys, cutting tools and other products. The performance of SG abrasives is better than similar corundum grinding tools, and the price is much lower than cubic boron oxide grinding wheels CBN and diamond grinding tools. Since SG abrasives are more expensive than ordinary abrasives, companies usually use them with other abrasives to achieve the best cost performance.

According to the “2022-2026 China SG Abrasives Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center, At present, global SG abrasive suppliers mainly include American Norton, American 3M, Norton Company, German Hermes Company, Fujian Blue Gold, Luxin, Qingdao Sisha Taiyi, Qingdao Recker New Materials, etc. Among them, American Norton is a subsidiary of Saint-Gobain of the United States. , is one of the first companies in the world to develop SG abrasives. Different SG abrasive manufacturers have different product codes, including Cubitrion, CA, BCA, SG-S, CB, etc.

The SG abrasive process route is divided into two types. One is the spherical accumulation crystal form developed by Saint-Gobain, and the product color is mainly white. The other is the layer accumulation crystal form developed by 3M, and the product color is mainly blue. SG abrasives were developed in the 1980s, but it was not until the 21st century that SG abrasives were applied in batches. Compared with the European and American markets, the development and application of SG abrasives in my country started late, and batch market application was achieved around 2017.

At present, the global SG abrasives market is still concentrated in the European, American, Japanese and Korean markets. SG abrasives account for about 22.0% of the abrasives market, while in China, this proportion is less than 5.0%. From this point of view, my country’s The SG abrasives market has broad development space. There are many SG abrasive manufacturers in my country, but due to scattered production capacity and backward technology, domestic SG abrasives are mostly concentrated in the mid- to low-end fields and do not yet have the ability to compete with international brands in the high-end fields.

Industry analysts said that SG abrasives are a new generation of abrasives that have certain advantages in performance, efficiency, cost, etc., and are expected to replace them in the future Ordinary corundum abrasive. The research and development and application of SG abrasives in my country started relatively late, and there is still a certain gap compared with the international market. SG abrasives are more suitable for enterprise automation needs. Under the background of consumption upgrading and Industry 4.0, the market demand for SG abrasives will be further released, and the future development prospects of the industry are good.
