What are the application fields of powder metallurgy?

Powder metallurgy is a process technology for making metal or using metal powder as raw material, forming and sintering, manufacturing metal materials, composites and various types of products. Powder metallurgy technology can reduce alloy composition segregation as much as possible and eliminate coarse and uneven casting structure.

In addition, powder metallurgy can easily realize multiple types of composites and give full play to the respective characteristics of each component material. It is a low-cost technology to produce high-performance metal matrix and ceramic composites. It can realize net near formation and automatic batch production, thereby effectively reducing production resources and energy consumption.

Powder metallurgy can make full use of ores, tailings, steelmaking sludge, steel mill scale, and recycling waste metals as raw materials. It is a new technology that can effectively regenerate and comprehensively utilize materials. It can produce materials and products with special structures and properties that cannot be produced by ordinary smelting methods.

Powder metallurgy related enterprises are mainly applicable to the production and research of spare parts in automobile industry, equipment manufacturing industry, metal industry, aerospace, military industry, instrumentation, hardware tools, electronic appliances and other fields, production of related raw materials and accessories, and manufacturing of various powder preparation equipment and sintering equipment. Products include bearings, gears, carbide tools, molds, friction products, etc. In military enterprises, heavy weapons and equipment such as armour piercing shells, torpedoes, aircraft tanks and other brake pairs need to be produced by powder metallurgy technology. Powder metallurgy auto parts have become the main market of China's powder metallurgy industry in recent years, and about 50% of auto parts are powder metallurgy parts.

(1) Application: (automobile, motorcycle, textile machinery, industrial sewing machine, electric tools, hardware tools, electrical appliances, engineering machinery, etc.) various powder metallurgy (iron copper base) parts.

(2) Classification: powder metallurgy porous materials, powder metallurgy antifriction materials, powder metallurgy friction materials, powder metallurgy structural parts, powder metallurgy tool and mold materials, and powder metallurgy electromagnetic materials and powder metallurgy high-temperature materials.

At present, China's total output value of powder metallurgy parts and bearings exceeds 5.5 billion yuan, accounting for a small proportion of the global market, and has a broad development space. Through the combination of continuous introduction of foreign advanced technology and independent development and innovation, China's powder metallurgy industry and technology are showing a trend of rapid development. It is one of the industries with rapid growth in China's general machinery parts industry. The output value of the national powder metallurgy industry increases at a very high rate every year.
