Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Prices for aluminium declined, and by the early 1890s, the metal had become widely used in jewelry, eyeglass frames, optical instruments, and many everyday items. Aluminium cookware began to be produced in the late 19th century and gradually supplanted copper and cast iron cookware in the first decades of the 20th century.
The Alcoa Care-free Home in New York State. Alcoa Care-free Homes are a group of suburban homes designed for Alcoa (Aluminum Company of America) by Charles M. Goodman during the Mid-century modern movement, incorporating ideas generated at the Women's Congress On Housing.

Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.
Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium.The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel, [1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery .
Aluminium–manganese alloys (AlMn alloys) are aluminium alloys that contain manganese (Mn) as the main alloying element. They consist mainly of aluminium (Al); in addition to manganese, which accounts for the largest proportion of about 1% of the alloying elements, but they may also contain small amounts of iron (Fe), silicon (Si), magnesium (Mg), or copper (Cu).
