Aluminium bronze

Aluminium bronze is a family of copper-based alloys containing 5 to 14 percent aluminum, first made in the 1850s and widely used for ship propellers and seawater pumps.

Aluminium chloride (AlCl3, also called aluminum trichloride) is an inorganic compound of aluminum and chlorine used as a powerful Lewis acid catalyst, chiefly for Friedel–Crafts alkylation and acylation.

Aluminium chlorohydrate

Aluminium chlorohydrate, also called aluminum hydroxychloride, is a group of water-soluble aluminum complexes best known as the active antiperspirant ingredient in most underarm products and also used as a coagulant in drinking water treatment.

Aluminium composite panel

An aluminum composite panel (ACP) is a flat building cladding of two thin aluminum sheets bonded to a polyethylene or mineral core, whose combustibility drove bans after the 2017 Grenfell Tower fire.

Aluminium conductor composite core

Aluminium conductor composite core (ACCC) is a high-temperature, low-sag overhead power conductor with a carbon and glass fiber composite core, first commercialized in 2005 by CTC Global.

Aluminium conductor steel-reinforced cable

Aluminium conductor steel-reinforced cable (ACSR) is a bare overhead conductor with aluminum wires stranded around a coated steel core, the standard for overhead transmission lines since the early 1900s.

Aluminium excess

Aluminium excess (ICD-11 5B91.4), body aluminium overload causing bone disease, encephalopathy, and infant neurodevelopmental harm, mainly in kidney failure, dialysis, and parenteral nutrition patients.

Aluminium foil

Aluminium foil, also called tin foil, is aluminum metal thinner than 0.2 mm used as barrier packaging and food wrap; the first rolling plant opened in Switzerland in 1910.

Aluminium gallium arsenide

Aluminium gallium arsenide (AlGaAs) is a III-V semiconductor alloy of aluminum arsenide and gallium arsenide whose band gap varies with aluminum content, making it the standard cladding material for GaAs-based devices.

Aluminium hydride

Aluminium hydride, also called alane, is a covalently bonded metal hydride that stores 10.1 wt% hydrogen and releases it rapidly at low temperature, making it a candidate storage material.

Aluminium hydroxide

Aluminium hydroxide, also known as aluminum hydroxide gel or algeldrate, is a white insoluble solid occurring as the mineral gibbsite, used to make alumina and as an antacid and vaccine adjuvant.

Aluminium nitride

Aluminium nitride (AlN) is a covalent ceramic nitride of aluminum that combines high thermal conductivity with strong electrical insulation, making it a leading substrate material for power electronics.

Aluminium nitride single-crystal growth

Aluminium nitride single-crystal growth is the production of bulk AlN crystals by physical vapor transport, yielding wafers used as substrates for deep-ultraviolet LEDs and power electronics.

Aluminium OS

Aluminium OS (ALOS) was the internal codename for Google's project merging ChromeOS and Android into a single desktop operating system, launched in September 2026 as Googlebook OS.

Aluminium oxide

Aluminium oxide (Al2O3), commonly called alumina, occurs naturally as corundum, the mineral behind ruby and sapphire, and serves as the feedstock for nearly all aluminum metal production.

Aluminium oxynitride

Aluminium oxynitride, often written ALON and marketed as ALON™, is a transparent ceramic combining glass-like optical clarity with high hardness, used in transparent armor, missile domes, and infrared windows.

Aluminium phosphide poisoning

Aluminium phosphide poisoning, also called rice pill or wheat pill poisoning, is fatal phosphine gas toxicity from the fumigant AlP; no antidote exists, mortality reaches about 27–70%, and NAC, oils, and ECMO show benefit.

Aluminium potassium sulphate dodecahydrate

Aluminium potassium sulphate dodecahydrate, KAl(SO4)2·12H2O, potassium alum or potash alum, a water-soluble double sulfate used as a mordant, water purifier, styptic, food additive (INS 522), and crystal deodorant.

Aluminium silicate

Aluminium silicate (kaolin, CAS 1332-58-7) is a kaolinite clay approved in the EU as a plant protection active substance used only as an insect repellent, applied up to 50 kg/ha, with approval extended to 31 March 2027.

Aluminium Stewardship Initiative

The Aluminium Stewardship Initiative (ASI) is a global non-profit standards and certification organization for the aluminum value chain, from bauxite mining through smelting and recycling, founded in 2015.

Aluminium sulfate

Aluminium sulfate, commonly called cake alum, is a water-soluble aluminum salt used chiefly as a coagulant in drinking water and wastewater treatment, and in paper making and dyeing.

Aluminium toxicity in people on dialysis

Aluminium toxicity in dialysis patients: accumulation from contaminated dialysate water and aluminium phosphate binders, causing dialysis dementia, osteomalacia, and microcytic anemia; prevented by reverse osmosis water and monitored via serum aluminium and DFO tests.
