Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
Aluminium–cerium alloys are typically cast, due to their excellent casting properties, although work has also been done to show that laser-based additive manufacturing techniques can be used as well to create parts with more complex geometries and greater mechanical properties. [75]
It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. [2] 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc, 2.1–2.5% magnesium, 1.2–1.6% copper, and less than a half percent of silicon, iron, manganese, titanium ...
6061 aluminium alloy (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [ 2 ]
AA 6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. The standard controlling its composition is maintained by The Aluminum Association. It has generally good mechanical properties and is heat treatable and weldable. It is similar to the British aluminium alloy HE9. 6063 is the most common alloy used for aluminium ...
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 ).
5052 is an aluminium–magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat treatable aluminum alloy, but can be hardened through cold working. [ 2 ] Chemical properties
6105 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the least common of the alloys in this series. While most wrought aluminium alloys are covered by multiple standards (from any mixture of ASTM, EN, ISO, and national standard bodies), 6105 is only dealt with in ASTM B221: Standard Specification for Aluminum and Aluminum-Alloy ...
