Welded aluminium alloy bicycle frame, made in the 1990s. An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc.
Aluminium alloys are alloys where the principal metal is aluminium. Subcategories. This category has the following 7 subcategories, out of 7 total. ...
Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium , iron , nickel and silicon ( AlCu(Mg, Fe, Ni, Si) ), often manganese is also included to increase strength (see aluminium-manganese alloys ).
This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Some of the main alloying elements are optionally listed after the alloy names.
The Unified Numbering System for Metals and Alloys (UNS) is an alloy designation system widely accepted in North America. Each UNS number relates to a specific metal or alloy and defines its specific chemical composition , or in some cases a specific mechanical or physical property .
Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion.
Aluminium–magnesium alloys (AlMg) – standardised in the 5000 series – are aluminium alloys that are mainly made of aluminium and contain magnesium as the main alloy element. Most standardised alloys also contain small additives of manganese (AlMg(Mn)). Pure AlMg alloys and the AlMg(Mn) alloys belong to the medium-strength, natural (not ...
Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of the metal. Almost all metallic aluminium is produced from the ore bauxite (AlO x (OH) 3–2x). Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions. [73]
