About Aluminium

Aluminium is soft, lightweight and silvery appearance metal. It is nonmagnetic and nonsparking. Aluminium is the most abundant metal in the Earth's crust, and the third most abundant element therein, after oxygen and silicon.

A brief history

The metal was first produced in 1825 (in an impure form) by Danish physicist and chemist HanAlPieces Christian Orsted. In 1886 the smelring process that still used today was discovered almost simultaneously by Charles Martin Hall in the US and Paul Louis Toussaint Héroult in France.  Before the Hall-Héroult process was developed, aluminium was exceedingly difficult to extract from its various ores. This made pure aluminium extremely valuable material, a precious metal, ranked alongside silver a nd gold. Bars of aluminium were exhibited at the Exposition Universelle of 1855 and Napoleon III, Emperor of France, said to have reserved a set of aluminium dinner plates for his most honoured guests. In 1888, Karl Bayer further improved the process, which greatly reduced the cost of aluminium - by around 80% - making it a commercial commodity.

Aluminium is metal for the future

Aluminium is the most widely used metal nowadays.

Pure aluminium has a low tensile strength, but when combined with thermo-mechanical processing, aluminium alloys display a marked improvement in mechanical properties, especially when tempered. Aluminium alloys form vital components of aircraft and rockets as a result of their high strength-to-weight ratio. Aluminium readily forms alloys with many elements such as copper, zinc, magnesium, manganese and silicon (e.g., duralumin). Today, almost all bulk metal materials that are referred to loosely as "aluminium", are actually alloys. For example, the common aluminium foils are alloys of 92% to 99% aluminium.

Aluminium has a lot of outstanding properties such as lightweight, strength, impermeability, conductivity, corrosion-resistant, durability, and flexibility. Such a great number of qualities turned it into very popular material. Aluminium widely used in products such as cars, trucks, aircrafts, utensil, food packaging, buildings, solar panels and other renewable energy equipment.



Even used aluminium is valuable - it is easily and endlessly recycled without quality loss. Recycling is critical to sustainable development. It allows resources to be saved and waste to be reduced. Aluminium makes a major and unique contribution to support product recycling into the future and to the benefit of society as a whole. Remelting used aluminium saves up to 95% of the energy needed to produce the primary product. Its unique recycling potential and intrinsic value means that aluminium is the most cost effective material to recycle. The market for used aluminium is steadily growing. The more aluminium in a product, the more chances of being recycled. Today, more than 30% of aluminium supply in highly developed countries comes from recycling and this percentage is quickly increasing.




The aluminium melting point is about  660 °C and the boiling point is about 2519 °C. The density is 2.70 g·cm−3 .Aluminium is a good thermal and electrical conductor, having 62% the conductivity of copper. It also has a great silvery reflectance ability.







Global society faces a great challenge to shift human economic activity and lifestyles on to a sustainable path in the 21st century.  The sustainability challenge shared by all nations, industries and communities is to provide not only for the basic needs of all of these people, but to meet their expectations for improving quality of life. The demand for aluminium products is increasing year by year, so its role in the lives of future generations is hard to overestimate.

  • The United Nations currently expect almost a half of the world population to live in megacities.
  • Aluminium is a good conductor of electricity and most overhead and many underground transmission lines are made of it. So the global Internet technology development and constant growth of computer quantity will  obviously increase demands in aluminium.
  • Since the Wright Brothers decided to put an aluminium engine in their first plane the rapid adoption and major role of aluminium has made possible the phenomenal growth of the aerospace industries. And future rapid development of aerospace technologies and further outer space exploration  will definitely need more and more of aluminium producing.
