A brief analysis of the development and trend of powder metallurgy industry in China in 2018

Powder metallurgy is preparing or metal powder with metal powder (or the mixture of metal powder and nonmetal powder) as raw materials manufacturing metal materials, composite materials and various types of products, technology belongs to the comprehensive technology of multidisciplinary cross, involves the chemical industry, metallurgy, material preparation, thermal, mechanical, disciplines such as automatic control technology. The process of powder metallurgy of guangdong da-hong new materials includes four steps: powder making, forming, sintering and post-treatment.

Powder metallurgy technology has a series of advantages such as energy saving, material saving, excellent performance, high precision and good stability, and is suitable for mass production. As a result of the difference from the common process, powder metallurgy has unique chemical composition and mechanical and physical properties which cannot be obtained by the traditional method of smelting. Powder metallurgy technology can be directly made into porous, semi-compact or full-compact materials and products, is a less cutting process. In addition, some materials and complex parts which cannot be prepared by traditional casting methods and mechanical processing methods can also be manufactured by powder metallurgy technology, so powder metallurgy technology has attracted much attention in the industry.

In recent years, the powder metallurgy industry has been developing rapidly, especially the automobile industry, machinery manufacturing, metal industry, aerospace industry, instruments and instruments, hardware tools, engineering machinery, electronic appliances and high-tech industry, which has brought greater development opportunities for the powder metallurgy industry. At present, powder metallurgy products are mainly used in automobile, household appliances, electric tools, motorcycle, agricultural machinery and engineering machinery industries, etc. The development of downstream industry will drive the development of upstream industry, and the capacity of the whole industry is constantly expanding.

From the perspective of the powder metallurgy machinery parts industry in the world, the largest sales market of the powder metallurgy parts is the automobile industry, and the field is also the market with the highest demand for the technology and quality of the powder metallurgy parts. In Europe, Japan and other industrial developed countries, the automotive industry demand for powder metallurgy parts accounted for about 90 percent of the powder metallurgy market, North America's powder metallurgy automotive parts accounted for more than 80 percent of the powder metallurgy industry market. From the point of view of the powder metallurgy machinery parts industry in China, the main market of the powder metallurgy parts industry has been the refrigerator compressor industry, air conditioner compressor industry, motorcycle industry, and gradually evolved into the automobile industry.

According to data from guangdong dahong new materials, the domestic powder metallurgy market is 6.4 billion yuan at present, of which automobile powder metallurgy parts are about 4 billion yuan. With the extensive application of automobile powder metallurgy products, it is assumed that China's automobile sales volume maintains a growth rate of 5%, and the usage amount of automobile powder metallurgy parts and bicycles reaches 15kg. It is estimated that China's automobile powder metallurgy market capacity will reach 14 billion yuan by 2020. On average, about 20kg of powder metallurgy parts are used for each vehicle manufactured by European and American automobile companies. On average, about 9kg of powder metallurgy parts are used for each vehicle manufactured by Japan automobile company. On average, only about 5kg of powder metallurgy parts are used in Chinese cars. China's powder metallurgy industry will have a large capacity expansion space in the future. With the further growth of automobile production and sales in China and the increase in the use of automobile powder metallurgy parts and bicycles, the automobile powder metallurgy market is expected to embrace relatively rapid development.
