aluminum
a·lu·mi·num A0235200 (ə-lo͞o′mə-nəm)n. Symbol Al A silvery-white, ductile metallic element, the most abundant in the earth's crust but found only in combination, chiefly in bauxite. Having good conductive and thermal properties, it is used to form many hard, light, corrosion-resistant alloys. Atomic number 13; atomic weight 26.9815; melting point 660.32°C; boiling point 2,519°C; specific gravity 2.70; valence 3. See Periodic Table.

Toxicology
Changes of aluminium toxicity include vitamin D-refractory osteodystrophy with impaired mineralisation, decreased bone formation, hypercalcaemia, anaemia, progressive encephalopathy, dementia (the data on aluminium and dementia are controversial).

AluminumThe most abundant metal in the crust of the Earth. Because it is not very dense and is resistant to corrosion, it has a wide variety of commercial uses, notably in transportation, packaging, and construction. It is also used in home appliances. Aluminum is also spelled aluminium, especially in countries where British English predominates.AcronymsSeeair lockaluminum
