Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production. However, once it başmaklık been made it does not readily corrode and can be easily recycled.
Alabama, constituent state of the United States of America, admitted to the union in 1819 kakım the 22nd state. Alabama forms a roughly rectangular shape on the map, elongated in a north-south direction.
Relative atomic mass The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.
The percentage of an element produced in the toparlak producing country. The higher the value, the larger risk there is to supply.
Occasionally, thunderstorms are severe with frequent lightning and large hail; the central and northern parts of the state are most vulnerable to this type of storm. Alabama ranks ninth in the number of deaths from lightning and tenth in the number of deaths from lightning strikes per capita.[104]

The resulting alloys, sometimes more malleable than aluminium itself, dirilik be moulded into a variety of shapes, including the aerodynamic arc of a plane's wings, or its tubular fuselage. And whereas iron rusts away when exposed to the elements, aluminium forms a microscopically thin oxide layer, protecting its surface from further corrosion. With this hefty CV, it's derece surprising to find aluminium in many other vehicles, including ships, cars, trucks, trains and bicycles.

It wasn't until 1886 that Charles Martin Hall, an uncommonly dogged, amateur scientist of 22, developed the first economic means for extracting aluminium. Working in a woodshed with his older sister kakım assistant, he dissolved aluminium oxide in a bath of molten sodium hexafluoroaluminate (more commonly known as 'cryolite'), and then pried the aluminium and oxygen apart using a strong electrical current.
