Aluminium 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. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, nonmagnetic, and ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the twelfth-most common element in the universe. The radioactivity of 26Al is used in radiometric dating.
Duralumin is a trade name for one of the earliest types of age-hardenable aluminium–copper alloys. The term is a combination of Dürener and aluminium. Its use as a trade name is obsolete. Today the term mainly refers to aluminium-copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 and 2024 alloys used in airframe fabrication.

AMAG is the biggest company in the Austrian Aluminium industry sector. It is situated in the village of Ranshofen, which is in Braunau am Inn.
Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al2O3) refined from raw bauxite by use of the Bayer and Hall–Héroult processes.
Novelis Inc. is an American industrial aluminum company, headquartered in Atlanta, Georgia, United States. It is an independent subsidiary of multinational aluminium and copper manufacturing company Hindalco Industries. Novelis is a producer of rolled aluminum and an aluminum recycler. The company serves customers in sectors including beverage cans, automotive, aerospace, consumer electronics, construction, foil and packaging.
An aluminium alloy (UK/IUPAC) or aluminum alloy is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.
Aluminium–lithium alloys are a set of alloys of aluminium and lithium, often also including copper and zirconium. Since lithium is the least dense elemental metal, these alloys are significantly less dense than aluminium. Commercial Al–Li alloys contain up to 2.45% lithium by mass.
6061 aluminium alloy is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. It has good mechanical properties, exhibits good weldability, and is very commonly extruded. It is one of the most common alloys of aluminium for general-purpose use.
7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the alloys from the 2000 series. It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts.
Alclad is a corrosion-resistant aluminium sheet formed from high-purity aluminium surface layers metallurgically bonded to high-strength aluminium alloy core material. It has a melting point of about 500 °C (932 °F). Alclad is a trademark of Alcoa but the term is also used generically.
Alusil as a hypereutectic aluminium-silicon alloy contains approximately 78% aluminium and 17% silicon. This alloy was theoretically conceived in 1927 by Schweizer & Fehrenbach, of Badener Metall-Waren-Fabrik, but practically created only by Lancia in the same year, for its car engines. It was further developed by Reynolds, now Rheinmetall Automotive. In the United States, Chevrolet was the first to use Reynolds A390 in the Chevrolet Vega.
Aleris Corporation was an American aluminum rolled products producer, based in Beachwood, Ohio. The company had approximately 5,000 employees globally as of mid 2015.
Hydro Extruded Solutions is a manufacturer of extruded aluminium profiles. Norsk Hydro announced in July 2017 that it would take full ownership of the 50/50 joint venture Sapa AS by buying the remaining 50 percent stake from conglomerate Orkla Group. The transaction was completed and Sapa was brought into Hydro ASA on October 2, 2017. According to Bloomberg, Sapa "falsified thousands of certifications for aluminum parts over 19 years for hundreds of customers, including NASA." In Extruded Solutions, Hydro has the largest global aluminium extrusion-based operation in the world, counting 100 production sites in more than 40 countries, and has 22,400 employees. Hydro's head office is located in Oslo, Norway.
The Aluminum Association is a trade association for the aluminum production, fabrication and recycling industries, and their suppliers. The Association is a 501(c)(6) non-profit organization based in Arlington, Virginia, United States.
An inclusion is a solid particle in liquid aluminium alloy. It is usually non-metallic and can be of different nature depending on its source.
Mitsubishi Materials Corporation, or MMC, is a Japanese company. It is a manufacturer of cement products, copper and aluminum products, cemented carbide tools, and electronic materials. It is one of the core companies of Mitsubishi Group.
Desjardin is one of the longest-running French metal packaging manufacturers, founded in 1848. The company produces and exports packaging for multiple industries, including the pharmaceutical industry, the cosmetic industry or the food industry. Desjardin places emphasis on sustainable solutions for its packaging materials and its tools.
Aircraft recycling is the process of scrapping and disassembling retired aircraft, and re-purposing their parts as spare parts or scrap. Airplanes are made of around 800 to 1000 parts that can be recycled, with the majority of them made from metal alloys and composite materials. The two most common metal alloys are aluminum and titanium and the main composite material is carbon fiber.
Aluminium-based nanogalvanic alloys refer to a class of nanostructured metal powders that spontaneously and rapidly produce hydrogen gas upon contact with water or any liquid containing water as a result of their galvanic metal microstructure. It serves as a method of hydrogen production that can take place at a rapid pace at room temperature without the assistance of chemicals, catalysts, or externally supplied power.
