1. Easy to process.     

After adding certain alloying elements, cast aluminum alloys with good casting properties or deformed aluminum alloys with good plasticity can be obtained.      

2. Good electrical and thermal conductivity.     

Aluminum's electrical and thermal conductivity is second only to silver, copper and gold.      

3. Small density.     

The density of aluminum and aluminum alloy is close to 2.7g/, which is about 1/3 of iron or copper.     

4. High strength.     

Aluminum and aluminum alloys have high strength, and the strength of the matrix can be strengthened by a certain degree of cold working, and some grades of aluminum alloys can also be strengthened by heat treatment.     

5. Good corrosion resistance.     

The surface of aluminum is easy to naturally produce a dense and firm AL2O3 protective film, which can well protect the matrix from corrosion.
