In 2014, by contrast, the US ranked sixth in primary aluminum production, and provided only 3.5% of world production. US production of primary aluminum peaked in 1980 at 4.64 million metric tons. Since then, US primary aluminum production has fallen by more than half, but secondary production has increased, making up much of the difference.
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.
This is a list of countries by primary aluminium production in 2023. [1] Primary aluminium is produced from aluminium oxide which is obtained from bauxite and excludes recycled aluminium. Only countries with a minimum production of 100,000 tonnes are listed.
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery .
LME Aluminium (or LME Aluminum in American and Canadian English) stands for a group of spot, forward, and futures contracts, trading on the London Metal Exchange (LME), for delivery of primary Aluminium that can be used for price hedging, physical delivery of sales or purchases, investment, and speculation.

The following is a list of countries by raw aluminium exports. Data is for 2021, in millions of United States dollars, as reported by The Observatory of Economic Complexity. Currently the top ten countries are listed.
Note that the term aircraft aluminium or aerospace aluminium usually refers to 7075. [65] [66] 4047 aluminium is a unique alloy used in both the aerospace and automotive applications as a cladding alloy or filler material. As filler, aluminium alloy 4047 strips can be combined to intricate applications to bond two metals. [67]
