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