Powder Metallurgy Products Have Various Applications

Powder metallurgy products have various applications:

1. Automotive parts: In order to improve fuel efficiency and control emissions, the working conditions of automotive engines have become more severe. By using powder metallurgy valve seats, valve guides, VCT and chain wheels, high strength, wear resistance and heat resistance can be achieved. Transmission components such as near-net shape synchronizer rings are combined with dual friction materials and high strength materials to produce some of the world's best clutch hubs. In addition, high-strength components such as hand-held gear wheels and shift forks can be made by high-temperature sintering.

2. Aerospace industry: Powder metallurgy materials used in the aerospace industry fall into two categories. One type is special functional materials such as friction materials, wear-resistant materials, sealing materials, and filtering materials. These are mainly used for auxiliary machines, instruments, and on-board equipment of aircraft and engines. The other type is high-temperature and high-strength structural materials, mainly used for important structural components of aircraft engines, such as aviation brake gears, aviation filters, and aviation turbine powder discs.

3. Household appliances: Some materials and components of household appliances can only be made by powder metallurgy, such as porous self-lubricating bearings in refrigerator compressors, Smart mirror TV bathroom, washing machines, and electric fans. Some materials and components of household appliances can be made with better quality and lower cost by powder metallurgy, such as complex shape gears and magnets in air conditioning fans and vacuum cleaners.

4. Electric and electrical tool parts: More than half of the various gears used in most electric tools are powder metallurgy parts, as well as some shaft sleeves, ratchets, and so on. Therefore, electric tool components are also a major application field for powder metallurgy parts. Powder metallurgy products have outstanding cost performance advantages in this field. Although the profit margin of electric tools is relatively low, there is still a certain profit margin for demanding professional electric tools.

In summary, powder metallurgy technology is a kind of forming technology, which is near-net shaping, rapid shaping, relatively saving materials and costs, and has higher efficiency, quality and effect compared to traditional forming and processing techniques. Currently, it has been widely applied in various fields.
