With the rapid development of the world's industry, in this century 2013 we ushered in the world's fourth industrial revolution, now our science and technology and global industry has entered the era of industry 4.0, in this new revolutionary era, not only the revolutionary innovation of information big data, for the field of cemented carbide, also produced a major breakthrough and change, The super cemented carbide produced by Jingang Seiko has relied on a strong scientific research background for many years, and is specialized in the research and development of the superhard superalloy field. After more than ten years of painstaking cultivation, it has successfully overcome the machining technology problems of various kinds of difficult materials such as superalloys. I believe that everyone has a preliminary understanding of "what is super carbide" and "how is super carbide made", and today we will talk about what use super carbide has and how to play a big role in various fields.

Super cemented carbide material on the basis of universal cemented carbide composition, add rhenium, ruthenium, osmium, molybdenum, vanadium, tantalum, niobium and other superalloys in one or several refractory high-temperature metal components, so that compared with ordinary cemented carbide, it has more excellent high strength, high hardness, high temperature resistance and other characteristics. Among them, the most obvious point is that the addition of trace rhenium elements in cemented carbide can greatly improve and improve the physical properties of cemented carbide materials, especially red hardness and alloy stiffness (elastic modulus). Rhenium can strengthen the solid solution of the original bonding phase metal (iron, cobalt, nickel) in the cemented carbide, so that the "industrial tooth" material, which is originally high in hardness, is more like a tiger. Especially in response to nickel-based superalloys, heat-resistant stainless steel, titanium alloy, tungsten, molybdenum, tantalum, niobium, zirconium and hafnium special alloys such as difficult to process materials of high-speed cutting and precision processing, the use of super carbide new materials prepared cutting tools and mold products, has an extraordinary cost-effective replacement advantages. This for the military industry, aerospace, precision and efficient machining, new energy, automobile, 3C, metallurgy, oil drilling, mining tools and other industries, and in the high-tech weapons and equipment manufacturing, cutting-edge science and technology progress and nuclear energy and other fields have made outstanding contributions, for the era of industrial Revolution 4.0, added a strong ink.

First of all, in the aerospace field where the high-performance use of super cemented carbide is particularly prominent, in the 1970s, the rapid development of aviation and the outbreak of the energy crisis caused a sharp rise in fuel prices, improving the fuel efficiency of turbine engines, and becoming a top priority for the aviation industry. In the field of aerospace, in addition to high strength and low expansion performance, super cemented carbide also has good resistance to hydrogen environmental brittleness, especially resistance to atmospheric high pressure hydrogen brittleness, and can be used for the construction of rocket engine main combustion chamber, accelerator, spring, turbo pump, exhaust duct, nozzle, bolt and other hydrogen environment service. A rocket engine in the United States used more than 100 kilograms of high temperature cemented carbide, accounting for 5% of the total weight of the engine, in addition, due to the aerospace field, commonly used to resist high temperature ceramic materials, and the connection of ceramic materials with low expansion coefficient also requires the participation of super cemented carbide, especially the new generation of high thrust ratio engine must be of high quality materials. The common characteristics of the "rhenium effect" in Diamond Seiko Super cemented carbide are creatively grafted and transplanted into traditional cemented carbide materials with the advantages of high strength, high temperature resistance and high heat resistance. Through the use of practice in the field of aerospace, it is found that the addition of super carbide cutting tools with rhenium, ruthenium and other components has greatly improved its high temperature red hard energy, mechanical properties and comprehensive service life, processing efficiency and processing accuracy.

Secondly, in China's military applications, super cemented carbide also occupies a pivotal position, "a generation of weapons, a generation of materials." In all eras, the most advanced technologies often first served military applications. Materials play a pivotal role in the defense industry, and new military materials are a prerequisite for the development of high-end weapons and equipment. In the case of aero-engines, half of the improvement in performance depends on materials. According to the "Development trend of aero engines and their demand for materials", it is predicted that the contribution rate of new materials, new processes and new structures to the thrust-weight ratio of 12-15 primary engines will reach more than 50%, and from the future development point of view, it can even account for about 2/3. It can be said that without advanced materials and manufacturing technology, there is no more advanced aircraft engine. Therefore, new military materials are the material basis of a new generation of weapons and equipment, and are also the key technologies in today's world military field. Countries all over the world attach great importance to the development of new material technology for military use, and accelerating the development of new material technology for military use is an important prerequisite for maintaining military leadership. New models and new equipment are increasing, and the demand for high-performance materials has increased significantly. At present, in the application of new weapons and equipment, high-performance military materials such as titanium alloy, super carbide, and composite materials (carbon fiber, etc.) stand out, and the market space is growing. In terms of the demand for materials in the aviation field, super cemented carbide is currently used extensively in body structure materials, and the amount continues to reach new highs. With its high temperature resistance, high strength, corrosion resistance, fatigue resistance and other characteristics, it is widely used in aerospace, ships and warships, and is an important material basis for the development of power plants to higher performance.

The "big plane" is ready for development, and the civil aircraft market is on the rise. At the 13th China Air Show, COMAC announced the latest "COMAC Market Forecast Annual Report (2021-2040)", while Boeing also released the latest China civil aviation market outlook report, both raised the market space of China's civil aircraft, is expected in the next 20 years, the civil aircraft market space between 9-9.5 trillion. Then with the advent of C919, will promote the global civil aircraft market pattern from the original "AB" to "ABC" development. In the environment of autonomy requirements, for these upstream material companies supporting aviation military aircraft, it will provide a new market increment.
