Introduction
Since aluminum has very abundant reserves and many excellent properties, it is widely used in industry and life. Below we will briefly introduce the applications of aluminum based on its properties.
A. Low density
The density of aluminum alloy power cable is 2.7g/cm³ (one-third of the density of iron and copper). It has good ductility and its conductivity is two-thirds of copper wire, but its quality is only one-third and its price is relatively low. It is cheaper and widely used in the manufacturing of high-voltage wires, cables, and radio industries. The density of pure aluminum is relatively low, but the density and hardness of aluminum alloys have been greatly improved. At present, aluminum alloys have been widely used in manufacturing industries such as aircraft, automobiles, trains, and ships. In addition, space rockets, space shuttles, and artificial satellites also use a large amount of aluminum and its aluminum alloys.
