Aluminium is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms 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, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating.
A tin foil hat is a hat made from one or more sheets of aluminium foil, or a piece of conventional headgear lined with foil, often worn in the belief or hope that it shields the brain from threats such as electromagnetic fields, mind control, and mind reading. The notion of wearing homemade headgear for such protection has become a popular stereotype and byword for paranoia, persecutory delusions, and belief in pseudoscience and conspiracy theories.
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Due to their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage (CV) product per unit volume than ceramic capacitors or film capacitors, and so can have large capacitance values. There are three families of electrolytic capacitor: aluminum electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors.
Aluminium foil is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm ; thinner gauges down to 6 micrometres are also commonly used. In the United States, foils are commonly measured in thousandths of an inch or mils. Standard household foil is typically 0.016 mm thick, and heavy duty household foil is typically 0.024 mm. The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
Reynolds Group Holdings is a New Zealand based packaging company with roots in the former Reynolds Metals Company, which was the second-largest aluminum company in the United States, and the third-largest in the world. Reynolds Metals was acquired by Alcoa in June 2000.
Fria is a town and Sub-prefecture in Lower Guinea, lying north of Conakry near the Amaria Dam on the Konkouré River. As of 2014 it had a population of 61,691 people.
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel, bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.
Blister pack is a term for several types of pre-formed plastic packaging used for small consumer goods, foods, and for pharmaceuticals.
Tin foil, also spelled tinfoil, is a thin foil made of tin. Tin foil was superseded after World War II by cheaper and more durable aluminium foil, which is still referred to as "tin foil" in many regions.
Sayanogorsk is a town in the Republic of Khakassia, Russia, located on the left bank of the Yenisei River, 80 kilometers (50 mi) south of Abakan, the capital of the republic. Population: 49,887 (2010 Census); 50,255 (2002 Census); 50,188 (1989 Census).
Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves controlled heating an electrically conducting object by electromagnetic induction, through heat generated in the object by eddy currents.
Arabkir, is one of the 12 districts of Yerevan, the capital of Armenia. Located to the north of the city centre, Arabkir is bordered by the Davtashen District from the northwest, Ajapnyak District from the west, Kentron District from the south, and Kanaker-Zeytun District from the east. Hrazdan River forms the natural border of the district from the north and the west. At the north, Arabkir has common borders with the community of Kanakeravan of Kotayk Province.

The Oslo Opera House is the home of the Norwegian National Opera and Ballet, and the national opera theatre in Norway. The building is situated in the Bjørvika neighbourhood of central Oslo, at the head of the Oslofjord. It is operated by Statsbygg, the government agency which manages property for the Norwegian government. The structure contains 1,100 rooms in a total area of 49,000 m2 (530,000 sq ft). The main auditorium seats 1,364 and two other performance spaces can seat 200 and 400. The main stage is 16 m (52 ft) wide and 40 m (130 ft) deep. The angled exterior surfaces of the building are covered with marble from Carrara, Italy and white granite and make it appear to rise from the water. It is the largest cultural building constructed in Norway since Nidarosdomen was completed circa 1300.

Aluminium capacitors are polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminium oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) (-) of the capacitor. A second aluminum foil called “cathode foil” contacts the electrolyte and serves as the electrical connection to the negative terminal of the capacitor.
Braidy Industries is an Ashland, Kentucky-based company, planning to become an aluminum alloys manufacturer for aluminum in the automotive and food and beverage industry. In October 2020 Braidy Industries announced that they are changing their name to Unity Aluminum.
