Physical properties of aluminum alloy

1, small density

The density of aluminum alloy is close to 2.7g/ m2, about one-third that of iron or copper.

2, high strength

Aluminum alloy strength is high, after a certain degree of cold processing can strengthen the matrix strength, some grades of aluminum alloy can also be strengthened by heat treatment.

3. Good electrical and thermal conductivity

Aluminum alloys are second only to silver, copper and gold in electrical and thermal conductivity.

4, good corrosion resistance

The surface of aluminum is easy to naturally produce a layer of dense and firm AL2O3 protective film, which can protect the matrix from corrosion. By artificial anodic oxidation and coloring, casting aluminum alloy with good casting performance or deformation aluminum alloy with good processing plasticity can be obtained.
