1, low density
The density of aluminum and aluminum alloys is close to 2.7g/, which is 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 processing can strengthen the matrix strength, some of the aluminum alloys can also be strengthened by heat treatment.
3, good electrical and thermal conductivity
The conductive and thermal conductivity of aluminum is second only to silver, copper and gold.
4, good corrosion resistance
The surface of aluminum is easy to naturally produce a layer of dense and strong AL2O3 protective film, which can well protect the substrate from corrosion. Through anodizing and coloring by hand, cast aluminum alloys with good casting properties or deformed aluminum alloys with good plasticity can be obtained.
5, easy processing
After adding a certain amount of alloying elements, cast aluminum alloys with good casting properties or deformed aluminum alloys with good plasticity can be obtained.
