Aluminium Element information, properties and uses

The resulting alloys, sometimes more malleable than aluminium itself, can 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.

Neocolonialism in Jamaica Debate Central

Bauxite, the red ore from which one extracts aluminum, is precious because supplies are scarce in the world. Foreign aluminum companies have invested in Jamaica as a result of rich deposits of bauxite, the supply of cheap labor, and the islands' political stability. Between 1950 and 1957 Jamaica became the world's largest producer of bauxite.

HAZARDOUS REACTIONS OF ALUMINUM POWDER

Prior to discovery of the Hall Heroult electrolytic process for reducing aluminum from bauxite ore in 1886, the cost of aluminum per kilogram exceeded that of most precious metals. As late as World War I the cost of aluminum was prohibitively high, which significantly limited the use of the metal in explosive mixtures. It was not until the mass
