Types of aluminum alloys

Aluminum alloys types mainly includes Al-Cu alloys, AI-Si alloys, AI-Mg alloys, AI-Zn alloys and so on.

There are many types of aluminum alloys. They can divide into many types according to different classification standards. The following are several common types of aluminum alloys:

1. Aluminum alloys types: Classification by alloy elements

  • Al-Cu alloys: contain copper, have good strength and corrosion resistance.
  • Al-Si alloys: contain silicon, usually used for casting alloys.
  • Al-Mg alloys: contain magnesium, have high corrosion resistance and welding performance.
  • Al-Zn alloys: contain zinc, have excellent corrosion resistance and welding performance

2. Aluminum alloys types:Classification by alloy state

  • Deformed aluminum alloys: such as 7xxx series alloys, widely used in the aerospace field.
  • Cast aluminum alloys: such as AZ91 magnesium alloys, commonly used in automotive and industrial applications.

3. Classification by application field

  • Aluminum alloys for automobiles: such as 2xxx series, 5xxx series, and 6xxx series. These alloys are widely used in automobile body panels due to their light weight and high strength.
  • Aluminum alloys for construction: such as 6063-T6, 6070-T5, etc. These alloys have good processing performance and corrosion resistance.
  • Aluminum alloy for ships: high strength and corrosion resistance, suitable for shipbuilding.

4. Classification by special properties

  • Heat-resistant aluminum alloy: such as heat-resistant aluminum alloy used for power transmission lines.
  • Functionally gradient aluminum alloy: different mechanical properties are achieved by changing the alloy composition and porosity.

Therefore, the above are some of the main classification methods of aluminum alloys, each of which has its specific application areas and performance characteristics. These aluminum alloys play an important role in modern industry and meet the material needs of different fields.
