What is aluminum?
Aluminum is a silvery-white metal that is highly malleable, corrosion resistant and thermally conductive, as well as lightweight. On the periodic table, aluminum’s chemical symbol is Al. It may be the most abundant metal in the Earth’s crust; however, it rarely exists on its own naturally. More typically, it is found in aluminum silicates, which refers to minerals such as bauxite and cryolite.
Bauxite mines are a large source of the world’s aluminum production. The bauxite is processed to obtain aluminum oxide, known as alumina. A colorless crystalline substance, alumina is sometimes used as a raw material in the ceramics and chemical processing industries. Its major use is as a starting material in smelters for the production of aluminum.
What is aluminum used for?
Aluminum has a wide range of uses, from food cans, foils and mirrors, to airplanes, electric vehicles and solar panels.
It is often alloyed with other metals, such as copper, magnesium, silicon, tin, zinc and manganese. Aluminum alloys are lightweight thanks to aluminum’s low density, making them desirable for use in aircraft, spacecraft and EVs.
Its flexibility and conductivity have also made it useful for applications such as high voltage power cables for transmission lines. Aluminum is also used in certain electric vehicle batteries, namely lithium-nickel-cobalt-aluminum oxide batteries, also called NCA batteries.
Aluminum demand trends
Fortune Business Insights states that the global aluminum market is set to grow at a CAGR of 6.2 percent between 2024 and 2032 to reach US$403.29 billion. The biggest driver of this growth will be the transportation sector, including aerospace, automotive and marine industries.
“This metal is highly preferred by automotive engineers and designers for its ability to reduce emissions and increasing fuel economy,” noted the research firm. “Electric vehicle manufacturers are incorporating this metal to reduce the weight of the vehicle and achieve a better driving range.”
For its part, Fact.MR estimates that the aluminum alloys market will exceed a value of US$327 billion by 2034. Cast aluminum alloys are now widely used in automotive and aerospace applications, the research firm’s report highlights, and growing demand for electric vehicles is driving the use of aluminum-tin alloys. This segment is expected to be a major growth driver for cast aluminum alloy sales going forward into the future.
Some of the biggest markets for aluminum are the United States, China and Germany. Aluminum alloys for infrastructure development and aircraft manufacturing are major sectors of demand growth in the United States. For China, its massive EV manufacturing industry is seen as a major source of demand growth for aluminum alloys, whereas in Germany, the broader automobile manufacturing industry is seen as a significant driver of demand growth.
Aluminum supply trends
The aluminum supply chain is complex due to the steps involved in the metal’s production.
The top aluminum producing countries are China, India and Russia. Worldwide aluminum production was 70 million metric tons (MT) in 2023. China, the biggest aluminum producer, produced 41 million MT — a record high for the second consecutive year. The country’s aluminum output is nearly six times higher than that of India and Russia combined.
Reuters attributed China’s record production in 2023 to “strong operations in some of China’s main producing regions, amid profitable conditions, and new projects, chiefly in the northern Inner Mongolia region, that came online.”
In terms of bauxite mine production, China ranks third behind Australia and the Republic of Guinea. Together, they represent 72 percent of the 400 million MT of bauxite produced globally in 2023. However, Australia and Guinea export the majority of their bauxite output to China.
It’s easy to see why the Asian nation has significant control of global aluminum supply. Investors interested in the aluminum market would do well to keep an eye on market trends in China as they can have an outsized role in influencing prices for the industrial metal.
However, supply from China has faced restrictions in years past — notably, the Chinese government has implemented anti-pollution policies that have affected its aluminum industry, which generates significant pollution. This has also led it to
But that’s not the only weight on China’s aluminum output. Higher energy prices have prompted Chinese smelters to slash aluminum production (an energy-intensive process) as a cost-cutting measure. China’s ongoing drought has also continued to strain the nation’s hydroelectric energy generation, and in turn its energy-intensive aluminum production.
Not surprisingly, the constraints on energy increased aluminum prices beginning in 2021 to levels not seen in over a decade. And this trend continued throughout 2023, resulting in a 9.1 percent boost in aluminum futures prices on the Shanghai Futures Exchange, reported Reuters.
For 2024, China is expected to post another record year of aluminum production due to more ample energy supply. The country’s hydropower reservoirs have benefited from heavy rains this year, resulting in a 22 percent increase in hydro generation in the first eight months of the year, reported Bloomberg. China also has vast stockpiles of coal to power its aluminum smelters if its hydropower fails to meet demand. As of November 7, 2024, aluminum futures prices were up more than 15 percent since the start of the year.

Aluminum futures
Aluminum futures, a derivative instrument tied directly to the price of the actual metal, are another option for those interested in aluminum investing. Futures are a financial contract between an investor and a seller. The investor agrees to purchase an asset from the seller at an agreed-upon price based on a date set in the future.
Rather than intending to take possession of the material asset, investors speculating in the futures market are instead making bets on whether the price of a particular commodity will rise or fall in the near future.
For example, if you buy an aluminum futures contract believing the price of metal is set to rise, and your prediction proves correct, you could gain a return on your investment by selling the now more valuable futures contract before it expires. However, be advised that trading futures contracts is not for the novice investor.
Aluminum futures are available for trade through the London Metals Exchange (LME) and CME Group.
The LME offers aluminum futures quoted in US dollars, with each contract representing 25 metric tons of aluminum, and aluminum alloy futures in contracts representing 20 metric tons.
The CME Group offers a suite of aluminum products, including aluminum futures and its newest product, aluminum options. While an aluminum futures contract only allows for trading on the date specified in the contract, aluminum options can be exercised at any time before they expire.
