What are the characteristics of aluminum?

General Characteristics. The unique combinations of properties provided by aluminum and its alloys make aluminum one of the most ver-satile, economical, and attractive metallic materials for a broad range ofuses—from soft, highly ductile wrapping foil to the most demanding engi-neering applications.

Which aluminum alloy is based on Al-Cu-Mg-Li?

Both 2xxxand 8xxxseries alloys based on the Al-Cu-Mg-Li system have beendeveloped. One of the earliest aluminum alloys containing lithium was 2020. Thisalloy in the T6 temper was commercially introduced in 1957 as a struc-tural alloy with good strength properties up to 175 °C (350 °F).

What is the unused series of aluminum?

Note that in Table 3, the 6xx.xseries is shown last and for cast alloys is designated as the unusedseries. The second and third digits identify the speci?c aluminum alloy or, forthe aluminum 1xx.x series, indicate purity.

How do you identify a specific aluminum alloy?

The second and third digits identify the speci?c aluminum alloy or, forthe aluminum 1xx.x series, indicate purity. If the greatest meanpercentage is common to more than one alloying element, the alloygroup is determined by the element that comes ?rst in sequence.

Domestic Production and Use: In 2020, three companies operated seven primary aluminum smelters in six States.

Two smelters operated at full capacity and four smelters operated at reduced capacity throughout the year. One

smelter operated at reduced capacity until it was idled in July. One other smelter remained on standby throughout the

year. Domestic smelters were operating at about 49% of capacity of 1.79 million tons per year at yearend 2020.

Production decreased by 8% after increasing in 2019. Based on published prices, the value of primary aluminum

production was about $1.98 billion, 17% less than the value in 2019. The average annual U.S. market price declined by about 11% from that in 2019. Transportation applications accounted for 40% of domestic consumption; in

descending order of consumption, the remainder was used in packaging, 21%; building, 14%; electrical, 8%;

consumer durables, 7%; machinery, 7%; and other, 3%. Salient StatisticsUnited States: 2016 2017 2018 2019 2020e

Recycling: In 2020, aluminum recovered from purchased scrap in the United States was about 3.2 million tons, of

which about 53% came from new (manufacturing) scrap and 47% from old scrap (discarded aluminum products).

Aluminum recovered from old scrap was equivalent to about 51% of apparent consumption.

Events, Trends, and Issues: Starting in March, many aluminum consumers shut down or reduced production in

response to the COVID-19 pandemic. Several manufacturers in the aerospace and automotive industries shut down

production facilities citing local government orders, agreements negotiated between the companies and the unions

representing employees, or decreased demand by retail consumers. Several extruders, rolling mills, and secondary

smelters decreased output or shut down in response to the COVID-19 pandemic. By July, most of the shutdowns

ended as safety measures were implemented. Consumption of aluminum for containers and packaging remained

steady as bars and restaurants were ordered closed by many local authorities, resulting in increased demand for

beverages in aluminum cans. Rolling mills and secondary smelters that produce can sheet increased imports of

U.S. Geological Survey, Mineral Commodity Summaries, January 2021 ALUMINUM

used beverage cans to make up for decreased supply from domestic can redemption centers that were closed in

most States. Primary aluminum smelters were exempted from the lockdown orders.

In March, a 252,000-ton-per-year smelter in Hawesville, KY, completed restarting one potline with 50,000 tons per

year of capacity after scheduled maintenance work. The restart of another 50,000-ton-per-year potline at the

Hawesville smelter was delayed because of economic conditions after maintenance work was completed. In July, a

279,000-ton-per-year smelter in Ferndale, WA, shut down four of its five potlines, citing high power prices and low

aluminum prices. The rest of its capacity was shut down previously.

On January 24, the President of the United States imposed a 10% tariff on imported products made with aluminum. In

March 2018, a 10% tariff was imposed on imports of aluminum but concerns had been raised that domestic

manufacturers were having to pay more for aluminum and that competitors were able to import finished products

without having to pay a tariff on the aluminum contained in finished products. Aluminum imports from all countries

except Argentina, Australia, Canada, and Mexico remained subject to the 10% ad valorem tariff as of early

December. The 10% tariffs were imposed under authority of section 232 of the Trade Expansion Act of 1962.

In March, the U.S. Department of Commerce initiated a countervailing duty investigation of imports of common alloy

aluminum sheet from 18 countries. The U.S. International Trade Commission initiated an antidumping investigation on

the same products from four countries. On August 10, the U.S. Department of Commerce issued its preliminary

determination of the countervailing duty investigation and set preliminary subsidy rates, with a final determination

expected by early 2021. The U.S. International Trade Commission was expected to issue its final determination in

February 2021. In June, the U.S. Department of Commerce issued its preliminary determination of the countervailing

duty investigation of foil imports from China and set preliminary subsidy rates.

World Resources:7 Global resources of bauxite are estimated to be between 55 billion and 75 billion tons and are

sufficient to meet world demand for metal well into the future.1

Substitutes: Composites can substitute for aluminum in aircraft fuselages and wings. Glass, paper, plastics, and

steel can substitute for aluminum in packaging. Composites, magnesium, steel, and titanium can substitute for

aluminum in ground transportation uses. Composites, steel, vinyl, and wood can substitute for aluminum in

construction. Copper can replace aluminum in electrical and heat-exchange applications. eEstimated.
