Hard alloy technology is not high enough, or faces the danger of being replaced by diamond

Cemented carbide starts with WC-Co alloy, which is the simplest and most widely used alloy. WC makes the alloy have good toughness and wear resistance. The competition in the field of hard alloys is very intense. Cemented carbide is still the main material for cutting, digging, etc., but it also faces the danger of being replaced by diamond in some applications.

Diamond is commonly known as "diamond drilling." This is what we often call diamonds. It is a mineral made of pure carbon. Diamond is the hardest material in nature. The use of diamonds is very extensive, for example: handicrafts, cutting tools in the industry. Carbon can form diamond at high temperature and high pressure. Synthetic diamond, also known as industrial diamond, has been developing rapidly in China for the last ten years. The total output has accounted for more than 90% of the total amount of the world. The diamond used in industry has excellent strength properties. Diamond-related diamond tools are mainly used for drilling, cutting, cutting, grinding, throwing, grinding and other geology, stone, construction, industrial processing, precision instruments, aerospace, electronic and other fields, also known as super abrasive He and ordinary abrasives (corundum and silicon carbide) are collectively referred to as "industrial teeth" and play a crucial role in China's economic development.

At present, due to the rapid development of the diamond industry, many new diamond tools are being produced at a rapid rate, and some of them far exceed the performance of traditional carbide tools. With the development of the times and the depletion of metal resources, carbides are in danger of being replaced by diamonds in some applications. Carbide products produced by domestic companies have a high degree of homogeneity in quality. Compared with foreign companies, the technical level is significantly different. At present, domestic companies are unable to make large carbide products and can only produce small bars and plates. A technical gap is difficult to catch up in the short term.
