Aluminum is a metal material with a large amount of use and a wide range of applications among non-ferrous metals, and its application range is still expanding.

The advantages and characteristics of aluminum are as follows:
1. Low density. The density of aluminum is about 2.7g/cm3. Its density is only 1/3 of that of iron or copper.
2. High plasticity. Aluminum has good ductility, and can be made into various products through extrusion, stretching and other pressure processing methods.
3. Corrosion resistance. Aluminum is a highly electronegative metal, and a protective oxide film will be formed on the surface under natural conditions or anodic oxidation, which has much better corrosion resistance than steel.
4. Easy to strengthen. The strength of pure aluminum is not high, but its strength can be improved by anodizing.
5. Easy surface treatment. Surface treatment can further enhance or change the surface properties of aluminum. The aluminum anodizing process is quite mature and the operation is stable, and it has been widely used in the processing of aluminum products.

6. Good electrical conductivity, easy to recycle.
