The role of powder metallurgy in industrial development

The development of industrial technology has not only provided the power for the social development, but also put forward higher requirements for our corresponding industries. As for the traditional metallurgy technology, we can easily find its shortcomings from some of the products in the past, for example, the hardness of the products is too high, the purity is too low, which makes it far from the production requirements in the industry. The production of powder metallurgy products has brought about a wide range of applications. Powder metallurgy is commonly used in the application and manufacture of machinery, hardware tools, electronics industry and precision instruments. Powder metallurgy can be seen from both general and top end technologies. Therefore, powder metallurgy products are widely used.

As a high precision production technology, powder metallurgy can produce large quantities of precision products and high quality parts. Powder metallurgy can be used to produce high performance alloy materials with uniform structure and difficult processing, which can not be produced by conventional process.

Through enhanced densification production processes, special alloy materials and some composite parts containing mixed materials can be produced. It can be seen that powder metallurgy products and other products have great differences and advantages in technology.

Powder metallurgy products have unique chemical and mechanical and physical properties, which can not be achieved by traditional casting method. The use of powder metallurgy products can greatly reduce the segregation of alloy material composition, eliminate the uneven casting structure, and improve the performance characteristics of powder metallurgy products.

After many years of in-depth research and discussion on the technology, the new technology of powder metallurgy has played a very good role in promoting modern production, and is more competent for modern production and development. The raw material can be metal powder or a mixture of metal and non-metal powder. After the molding and sintering treatment, it is then processed through various types of processes.

In the process of discussion and research, people combine independent innovation and research with foreign exchanges, especially the introduction of some technologies. In recent years, P/M industry and technology of our country have developed rapidly. In particular, the parts industry has become a fast growing sector in the machinery industry. At present, the annual output of China's powder metallurgy industry is growing at a rate of 35 percent, while global manufacturing has accelerated China's entry pace. Especially in the automobile industry, aerospace industry, construction machinery and other fields. It has brought huge market and broad development prospect for powder metallurgy.

Therefore, the development of powder metallurgy in the new era has written a more brilliant chapter for Chinese industry.
