First, it is easy to process. After adding certain alloying elements, forged aluminum alloy with outstanding forging function or deformed aluminum alloy with good processing plasticity can be obtained.

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

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

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