1. Low density: The density of aluminum is 2.7, which is about 1/3 of that of copper (8.9) or steel (7.8). The low density is very beneficial to the lightweight of vehicles such as aerospace vehicles, ships, vehicles and buildings. It can also save moving costs and processing costs, and greatly reduce production costs. The application in various fields such as industry, construction and civil use is more and more important. widely!

2. Good corrosion resistance and weather resistance: Aluminum and aluminum alloys can form a hard and dense oxide film with good corrosion resistance in the atmosphere. Further improve the corrosion resistance of aluminum!

3. Good decoration: Aluminum alloy has good plasticity and can be processed into various specifications and formed products. Through surface treatment, films of different properties and colors can be formed, and the decoration is also relatively good.

4. Good thermal conductivity: The thermal conductivity of aluminum is very high, second only to gold, silver, and copper among metals, and it is 3 times that of iron, and the same weight of aluminum is 12 times that of iron. Therefore, aluminum alloys are used to manufacture radiators. , Good material for heaters!
