Where is the use of aluminum, our daily life can not be separated from aluminum?

(1) The density of aluminum is very small, although it is relatively soft, it can be made into various aluminum alloys, such as hard aluminum, super hard aluminum, rust-proof aluminum, cast aluminum and so on. These aluminum alloys are widely used in aircraft, automobiles, trains, ships and other manufacturing industries. In addition, space rockets, space shuttles, artificial satellites also use a lot of aluminum and aluminum alloys. For example, a supersonic aircraft is made up of approximately 70% aluminum and its aluminum alloys. Aluminum is also used extensively in ship construction, and the amount of aluminum used in a large passenger ship often reaches several thousand tons.

(2) the conductivity of aluminum is second only to silver, copper and gold, although its conductivity is only 2/3 of copper, but the density is only 1/3 of copper, so the same amount of electricity is transmitted, and the quality of aluminum wire is only half of that of copper wire. The oxide film on the surface of aluminum not only has corrosion resistance, but also has certain insulation, so aluminum has a wide range of uses in the electrical appliance manufacturing industry, wire and cable industry and radio industry.

(3) Aluminum is a good conductor of heat, its thermal conductivity is 3 times greater than iron, and aluminum can be used in industry to manufacture various heat exchangers, heat dissipation materials and cookware.
