Aluminum

Aluminum metal is a silvery-white metallic element with the chemical symbol Al. Aluminum is the third most abundant metal in the earth's crust after oxygen and silicon, making it one of the very abundant metals on earth. Aluminum is also known as a light metal because of its low density, which is about 34.61% that of iron and 30.33% that of copper. Due to its tough and light texture, good ductility and electrical conductivity, aluminum is used in a wide range of applications. For example, it can be used to make structural materials for airplanes, vehicles, ships, rockets, and as a material for ultra-high voltage cables. In addition, pure aluminum is used to make everyday utensils, often referred to as "steel concentrate" or "steel seed".

Aluminum alloys are alloys formed by adding a certain amount of other alloying elements to aluminum as a base, and are one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys also have some specific characteristics of alloys depending on the type and amount of alloying elements added. Aluminum alloys are used in a wide range of applications, including aerospace, marine, chemical, metal packaging, and many other industries.
