Aluminum is the most abundant metal and the third most abundant element, after oxygen and silicon, in the earth's crust. It is widely distributed and constitutes approximately 8 percent of the earth's surface layer. However, aluminum is a very reactive element and is never found as the free metal in nature. It is found combined with other elements, most …

Physical Properties of Aluminium. Aluminium has a lower density than any other commercial metal except magnesium. Given the right type of surface, aluminium makes an excellent reflector, especially for ultraviolet light. Aluminium is an odourless, tasteless, silvery-white metal. With increasing silicon and ductile and quite soft.
Aluminum futures fell below $2,200 per tonne mark, extending the retreat from the five-month high of $2,347 on September 29th, tracking the decline for other base metals as the outlook of a hawkish Fed and a slowing Chinese economy hampered industrial sentiment. Still, supply concerns limited the downturn. China, the world's top producer and …

Aluminum is an abundant constituent of rock minerals; in fact, only oxygen and silicon exceed aluminum in abundance among the elements present in the outer part of the earth's crust. Aluminum is, however, a very minor dissolved constituent in natural water. In routine water analyses the element is seldom determined, but the ...
A tale of two spellings. Both aluminum and aluminium have a long history of use referring to the metallic element (commonly used as foil to cover food). They both date to the early 19th century, stemming from the word alumina. Aluminum became preferred in the United States and Canada, while aluminium became favored throughout the rest of the ...
Alloy Designations. Aluminium is most commonly alloyed with copper, zinc, magnesium, silicon, manganese and lithium. Small additions of chromium, titanium, zirconium, lead, bismuth and nickel are also made and iron is invariably present in small quantities. There are over 300 wrought alloys with 50 in common use.
