In the second half of the 20th century, aluminium gained usage in transportation and packaging. Aluminium förekommer inte i metallisk form i naturen. Olika användningsområden för aluminium.
World production continued to rise, reaching 58,, metric tons in Aluminium production exceeds those of all other non-ferrous metals combined. Nedan följer några exempel på användningsområden. Aluminium blev isoleret første gang i af H.C. Ørsted.
Vad är aluminium? - Svaren
Aluminium became much more available to the public with the Hall—Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in , and the Bayer process developed by Austrian chemist Carl Joseph Bayer in These processes have been used for aluminium production up to the present. Soon after its discovery, the price of aluminium exceeded that of gold. In the second half of the 20th century, aluminium gained usage in transportation and packaging.
World production of the metal grew from 6, metric tons in to 2,, metric tons in , when aluminium became the most produced non-ferrous metal , surpassing copper. See more. Tidligere har man traditionelt tildelt æren til den tyske kemiker Friedrich Wöhler, der udvandt aluminium som et gråt pulver i , men Wöhler har i et brev til Ørsted erkendt, at det er Ørsted, der har lavet det grundlæggende arbejde med at isolere metallet.
Discovery of this metal was announced in by Danish physicist Hans Christian Ørsted , whose work was extended by German chemist Friedrich Wöhler.
However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. The introduction of these methods for the mass production of aluminium led to extensive use of the light, corrosion-resistant metal in industry and everyday life. Aluminiumfolie används för .

Production began to shift from developed countries to developing ones ; by , China had accumulated an especially large share in both production and consumption of aluminium. År fanns industriell tillverkning av aluminium fortfarande endast i Salindres, Frankrike och den samlade årsproduktionen var 3–4 ton.[ 23] var världens största aluminiumstycke Washingtonmonumentets 2,85 kg tunga spets som kostade lika mycket som dagars lön för en arbetare.
The aluminum beverage can was introduced in Beer-maker Coors was the first to use the aluminum drink can. Aluminium används till det mesta, från stort till smått. Kontakta sidansvarig.

Ämnet upptäcktes av den franske kemisten Antoine Lavoisierin. Människan började tillverka saker i metall för ungefär år sedan. The most familiar story of the first extraction of aluminum is that the youthful Ohioan Charles Martin Hall developed aluminum’s electrolytic extraction process in his family’s woodshed in , patented the invention, helped found the company that would later become Alcoa, and died a rich man.

How was aluminum discovered?| History of Aluminum
Aluminium or aluminum metal is very rare in native form , and the process to refine it from ores is complex, so for most of human history it was unknown. Renaissance scientists believed that alum was a salt of a new earth ; during the Age of Enlightenment , it was established that this earth, alumina , was an oxide of a new metal. Aluminium was difficult to refine and thus uncommon in actual usage.
The metal became an exchange commodity in the s.
Aluminium began to be used in engineering and construction. Today, I bring you the victory over the Turk. It was reduced only after the initiation of the first industrial production by French chemist Henri Étienne Sainte-Claire Deville in In , metallurgist James Fern Webster was producing pounds of pure aluminium every week at his Solihull Lodge factory in Warwickshire , England , using a chemical process.
World production of the metal grew from 6, metric tons in to 2,, metric tons in , when aluminium became the most produced non-ferrous metal, surpassing copper. Aluminium production became a source of concern due to its effect on the environment, and aluminium recycling gained ground. Before then, "the packaging in primary use for pretty much all beverages was steel.
