Aluminium is a silvery-white, soft and ductile metal found in the boron group. It is the third most abundant element on Earth. Aluminium is well-known for its remarkable low-density. It creates a passivating layer in corroding environments, which protects it from further damage. Aluminium is alloyed with copper, zinc, manganese, magnesium, and silicon commonly.
Aluminium has 30% of copper’s density along with good thermal and electrical conductivity. It is also capable of superconductivity, with capabilities of conducting 1.2kelvin temperature and a magnetic field of 100 gauss. It is also the most common material used for fabrication of superconductors such as qubits. Aluminium is also the most widely used non-ferrous metals. Aluminium is used in transportation, food and beverage containers, packaging, construction, street lighting poles, cooking utensils, and electrical transmission lines. Corrosion resistance of aluminium is excellent as it forms a thin layer of aluminium oxide, which protects the metal from preventing oxidation. Aluminium can be alloyed with other elements to give it enhanced properties, while preserving the low density, which would make it usable in many applications.
