Cheap Black Synthetic Corundum Wholesale Price

Corundum is divided into natural corundum and artificial corundum. Natural corundum is a kind of pure alumina (Al2O3). The main mineral composition of artificial corundum is physical corundum. Artificial corundum is divided into brown corundum (a), white corundum (WA), chrome corundum (PA), zircon corundum (ZA), black corundum (BA), single crystal corundum (SA), microcrystalline corundum (MA), etc.

white aluminium oxide is mainly made of bauxite, iron filings and anthracite by melting and reducing impurities in the electric arc furnace. It is made of aluminum oxide powder by melting and crystallizing in the electric arc furnace. Other corundum is a material with different properties derived from the addition of a certain amount of other oxides in the melting process with different silicon carbide companies content. The corundum widely used are brown corundum and white corundum.

(cheap black synthetic corundum wholesale price)Shangpu consulting industry analysts pointed out that brown fused alumina Abrasives, known as "industrial teeth", are not only closely related to equipment manufacturing, aerospace, shipping, new energy, automobile, home appliances, electronic information and other industries, but also have penetrated into all aspects of people's lives. As one of the abrasives, China, India and Russia have become the largest markets for the sales growth of aluminum oxide abrasive products.

China will surpass the United States as the world's largest producer of pink corundum. At present, China has become a big consumer of artificial corundum, but it is not a powerful country. The international artificial corundum products are mainly concentrated in the middle and low-end market, with low technical content. Compared with the international advanced level, there is still a large gap. The international high-end technical products are lack, aluminum oxide grit mainly relying on export.(cheap black synthetic corundum wholesale price)

There is a big gap between the functions of high-end products and foreign products, and only 30% of the brown aluminum oxide products that can meet the needs of several pillar industries, such as automobile, aerospace, machine tools, bearings, locomotives and ships, mostly maintain the traditional medium and high-end level. synthetic corundum has a certain hardness and toughness, can be processed into different size range and uniform particle shape, with high temperature stability and chemical stability.

(cheap black synthetic corundum wholesale price)The hardness of silicon carbide price is 9, the microhardness of white corundum is 1800-2200kg / mm2, the microhardness of white corundum is 9, the microhardness of white corundum is 2200-2400kg / mm2, second only to diamond. Brown corundum and white corundum are the main materials for manufacturing consolidated abrasives, advanced refractories and black aluminium oxide products. They can also be used for antiskid, grinding, investment casting, advanced ceramics, etc.

According to the report on in-depth research and Prospect Forecast of China's white corundum industry in 2015-2020 released by Shangpu consulting industry investment decision network, the sales revenue of China's artificial corundum industry reached 18.38 billion yuan in 2013, up 8.9% year on year. In 2012, the sales revenue of China's brown fused aluminium oxide industry reached 16.882 billion yuan, an increase of 40.4% year on year.(cheap black synthetic corundum wholesale price)

Compared with green carborundum medium-sized enterprises, small-sized enterprises are weak in strength, weak in technological innovation, backward in production equipment and poor in product quality, which are in a disadvantageous position in the competition. From the perspective of sales areas: mainly concentrated in East China, South China and North China, these areas are also the concentration of white fused alumina price downstream industries.(cheap black synthetic corundum wholesale price)

China's brown fused aluminum oxide industry is dominated by small and medium-sized enterprises, especially small enterprises. From a regional perspective, China's artificial corundum production enterprises are mainly concentrated in East China and South China, especially in East China, which accounts for the vast majority. From a specific province perspective, Guizhou, Henan and Shandong Province are concentrated in artificial corundum production enterprises, which are the majority of black aluminum oxide media production enterprises in China.
