It is produced in many tempers, some of which are 7075-0, 7075-T6, 7075-T651. The first 7075 was developed in secret by a Japanese company, Sumitomo Metal , in 1935, [ 3 ] but reverse engineered by Alcoa in 1943, after examining a captured Japanese aircraft.
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.
New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T.

Aluminium (or aluminum in North American English) 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.
In 2000, the U.S. was the largest producer of primary aluminum. The six remaining smelters in the U.S. now make up a small percentage of global capacity.
7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
As of late 2019, the system of LME Aluminium contracts is associated with 1.27 to 1.49 million tonnes of physical primary Aluminium stored in 500 to 700 warehouses around the world, out of 2.78 million tonnes of global reported warehoused Aluminium, and 11.78 million tonnes of global reported and unreported warehoused Aluminium.
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
