Iron-based Powder Metallurgy Industry Development

---

Combined with the current status and downstream development prospects of iron-based powder metallurgy technology in my country and abroad, the future development direction of iron-based powder metallurgy mainly includes four categories:

Further improve the characteristics of high consistency, high precision, and complex shape of powder metallurgy, and serve for the upgrading of the industrial structure of machinery, automobiles, home appliances and other industries. Such directions are mainly oriented towards reducing the weight of machinery, saving energy consumption, reducing emissions, and miniaturizing the equipment for civilian use. For example, the powder metallurgy parts for VVT developed by Dongmu Co., Ltd. not only improve oil combustion, but also reduce automobile exhaust emissions more effectively.

Improve the density of iron-based powder metallurgy, and increase the range of powder metallurgy parts that can replace traditional forgings. At present, the density of mainstream-based powder metallurgy is 7.2-7.4g/cm3, and my country’s most technologically advanced Dongmu has increased its density to 7.6g/cm3. At this density, iron-based powder metallurgy has replaced automobiles, machinery, etc. Most connecting parts and some functional parts. Considering the saving of materials in powder metallurgy itself and its own environmental protection characteristics, in theory, the downstream space of such iron-based powder metallurgy parts can reach the level of 100 billion yuan.

To improve the electromagnetic properties of powder metallurgy parts, the goal is to replace materials such as silicon steel and ferrite. Taking oriented silicon steel as an example, the conductive principle of silicon steel is to reduce iron loss by reducing grain boundaries after adding silicon and other elements-especially oriented silicon steel, which is a single coarse grain in the guiding direction. Compared with the one-dimensional conduction direction of oriented silicon steel, powder metallurgy parts can realize multi-dimensional conduction in any direction, that is, forming a product is a single crystal grain. At present, this type of technology has achieved breakthroughs in a few companies. If it fully meets the industrial requirements, it will be widely used in transformers, motors, new energy vehicles and intelligent control systems including robots.

Further alloying, the goal is lightweight and functional. The iron-based powder is mixed with alloy powders such as aluminum, magnesium and rare earth elements to achieve its ultra-thin, lightweight and other properties, and can be widely used in fields closely related to life such as electronic devices and wearable devices.
