With the improvement of Chinese national defense science and technology strength, problems faced by Chinese aero engine will be alerted greatly. Let us recall Chinese aero engine development.

Researchers in the US and Korea say they have developed a new way to make a flexible, resistive random access memory (RAM) device in a room-temperature process – something that has proved difficult to do until now. 

Metal machinery manufacturing, machining is the most basic and reliable means of precision machining, mechanical, electrical, electronic and other modern industrial sector plays an important role. Machining technology development, the most recent history is the history of the development of the tool material. The new tool materials can greatly improve cutting production rate, improve processing accuracy, surface quality and expand the processing areas, reduce tool consumption, access to a huge economic benefits. The new tool materials for the development of machinery manufacturing plays a huge role in promoting. Therefore, the development, promotion and use of new materials is an important part of the new machinery manufacturing technology revolution.
Tungsten carbide is a new information tool, due to its high hardness, wear resistance and compressive strength, with more chaos chemical resistance, adhesion and heat resistance, excellent performance, and its tools high hardness materials cutting efficiency 5-10 times high speed steel cutting tools and machining speed steel cutting tools can not be processed, and therefore the tool data, according to a large proportion.

Meet the needs of modern science and technology development, to the precision of the direction, to enter since the seventies, in modern machining, cutting tools with carbide cutting inserts dimensional accuracy remarkable progress, therefore, carbide production manufacturers are constantly advances its product precision. For example, in some developed countries have phased out the U grade carbide precision. Many Carbide Die size has reached micron level precision, and even some have reached the end of ultrafine meter level.
Adaptation requirements produce sophisticated products, better technology and production equipment. Late sixties introduced carbide produced in the field of hot isostatic pressing, and seventies migration to Carbide production in the field of spray-drying technique, cemented carbide production process are a big step forward, In recent years, low-pressure hot isostatic clean burning equipment and technology to make carbide products density close to the theoretical value of up to 99.999%, significantly advances the quality of products.

In order to improve processing efficiency and adapt to the new requirements of automated machine tools, we developed a number of new carbide, such as ultra-fine fine carbide, gradient cemented carbide, carbide duplex, self-lubricating alloy, nanoscale hard alloy, super-hard coating layer of hard alloy. Meanwhile tungsten carbide industry forward depth processing tool areas.
Tungsten carbide consumption in our country although Unfettered unfolded after emerging industry, but carried out rapidly, especially after the reform and opening up, the emergence of independent growing trend. Currently, carbide production in the country has been in the forefront of the world, the product brands, models also more fully, and has many product quality has reached the international advanced level, the output value and profits to grow steadily.
