Compared with other metal materials, aluminum alloy has the following characteristics:

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

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

3. Good electrical and thermal conductivity. The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.

4. The surface of aluminum with good corrosion resistance is easy to naturally produce a dense and firm Al2O3 protective film, which can well protect the matrix from corrosion. Through artificial anodizing and coloring, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained.

5. It is easy to process. After adding certain alloy elements, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can be obtained.
