Aluminum is a chemical element. Its chemical symbol is Al, and its atomic number is 13. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and it is the most abundant metal element in the earth's crust. Among the metal varieties, second only to steel, it is the second largest category of metal. By the end of the 19th century, aluminum had emerged as a competitive metal in engineering applications and was popular. The development of three important industries of aviation, construction and automobile requires that the material properties have the unique properties of aluminum and its alloys, which is greatly beneficial to the production and application of this new metal aluminum. Aluminum is used in a wide range of applications.
Pure aluminum is very soft, has low strength, has good ductility, can be drawn into filaments and rolled into foil, and is used in a large number of wires, cables, radio industry, and packaging industries. Its conductivity is about two-thirds of that of copper, but because its density is only one-third that of copper, the conductivity of aluminum is about copper compared to aluminum and copper wires of equal mass and equal length. Doubled and the price is lower than copper.
