1145 Aluminium alloy is a nearly pure aluminium alloy with minor impurities like copper, manganese, magnesium, zinc, titanium, silicon and iron. [1]
The anodizing current varies with the area of aluminium being anodized and typically ranges from 30 to 300 A/m 2. Aluminium anodizing (eloxal or El ectrolytic Ox idation of Al uminium) [ 12 ] is usually performed in an acidic solution, typically sulphuric acid or chromic acid, which slowly dissolves the aluminium oxide.
Photosensitive anodized aluminum was qualified to Federal Specification GG-P-455 in 1965, a document that outlines the performance of Type 1 and Type 2 photosensitive anodized aluminum. [3] Since qualification to GG-P-455, photosensitive anodized aluminum has been specified by many military, government and industrial organizations, including:
Anodizing aluminum has been widely used since early last century for corrosion protection and decorative purposes. The porous nature of anodic alumina films was discovered in the 1930s [ 1 ] and further elaborated in the 1950s–1970s.
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.
An anodized aluminium sauté pan. Aluminium is a lightweight metal with very good thermal conductivity. It is resistant to many forms of corrosion. Aluminium is commonly available in sheet, cast, or anodized forms, [10] and may be physically combined with other metals (see below). Sheet aluminium is spun or stamped into form.
