Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production. However, once it özgü been made it does not readily corrode and gönül be easily recycled.

Alabama, constituent state of the United States of America, admitted to the union in 1819 as the 22nd state. Alabama forms a roughly rectangular shape on the map, elongated in a north-south direction.

Farther south lie the varied soils of a mineral belt, and these are succeeded by the rich limestone and marl soils of the Black Belt. The soils along the coast of Alabama consist of sandy loams and deep porous sands.

'I feel like I'm trapped in a tin box at 39000 feet'. It's a common refrain of the flying-phobic, but maybe they would find comfort in knowing that the box is actually made of aluminium - more than 66000 kilo of it, if they're sitting in a jumbo jet. While lamenting one's presence in an 'aluminium box' doesn't have quite the same ring, there are several good reasons to appreciate nalbur this choice of material. Pure aluminium is soft. However, alloying it with elements such bey such birli copper, magnesium, and zinc, dramatically boosts its strength while leaving it lightweight, obviously an asset when fighting against gravity.

In 1954, the U.S. Supreme Court ruled in Brown v. Board of Education that public schools had to be desegregated, but Alabama was slow to comply. During the 1960s, under Governor George Wallace, Alabama resisted compliance with federal demands for desegregation.

And you can catch up with the clink of zinc with Brian Clegg on next week's Chemistry in its element. I'm Chris Smith, thank you for listening and goodbye.

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 as 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.
