In this article, we will look at the 10 Best Aluminum Stocks To Buy According to Billionaires.
Aluminum is one of the most essential and versatile materials required by modern industries. It is known due to its unique qualities including its lightweight nature, corrosion resistance, and efficient recyclability. As industries move toward sustainability and efficiency, aluminum is seeing an increase in its demand. In 2023, its global market was valued at $229.83 billion, which is forecasted to grow to $403.29 billion by 2032, a compound annual growth rate (CAGR) of 6.2%, according to Fortune Business Insights. As demand rises for electric vehicles (EVs), green energy, and lightweight manufacturing, aluminum is becoming an attractive investment.
One of the big reasons why aluminum is seeing a rise in demand is its usage in electric vehicles. Heavier metals are being replaced with aluminum to increase fuel efficiency and driving range by automakers like BMW and Mercedes. The U.S. aluminum market is expected to reach $43.05 billion by 2032 as EV manufacturers ramp up the use of aluminum in order to make vehicles lighter and more energy-efficient. Furthermore, the aerospace industry also plays a key role in its demand. As global air travel recovers, Boeing and Airbus are ramping up production, relying heavily on aluminum alloys for fuselages and wings.
Additionally, the packaging industry is booming as companies make use of aluminum’s 100% recyclability. Aluminum-made beverage cans contain 3x to 12x more recycled material compared to other materials, resulting in less wastage and energy consumption, as per The Aluminum Association. The circular economy is gaining momentum as manufacturers rely on recycled aluminum in order to cut costs and emissions. Moreover, recycling aluminum saves energy that goes toward producing new metal, making it a leap forward in sustainability efforts.
While demand for aluminum increases, the trade war over metals is gaining traction. According to The New York Times, U.S. President Trump recently reintroduced 25% tariffs on imported aluminum to protect U.S. manufacturers. While this move will raise costs for automakers, beverage companies, and construction companies relying on imported aluminum, the domestic producers may benefit. On the other hand, Canada and European countries are retaliating with reprisal tariffs, increasing global supply chain uncertainty. Producing 45 million metric tons of aluminum annually, China has capped its output. This implies that the increasing demand will be fulfilled through recycling and secondary sources. Thus, the global supply chain can face uncertainties and lead to price rises as U.S. tariffs escalate trade tensions.
Furthermore, an important stride in the aluminum space is the increase of aluminum-ion batteries. These are considered potential alternatives for lithium-ion batteries, as they offer faster charging, longer lifespan, and decreased costs. According to Future Market Insights, the market for aluminum-ion batteries is forecasted to grow to $9.5 billion by 2035 due to demand for renewable energy and electric vehicles. Considering that aluminum is cheaper and more abundant than lithium, this transition could transform energy storage and transportation.
On the other hand, billionaire investors are increasing their investments in the aluminum industry, reflecting strong confidence in its growth potential. Blackstone CEO, who is supporting U.S. aluminum tariffs, expects domestic manufacturing to propel, as reported by Reuters. Concurrently, AI Circle reports that Malaysian tycoon Koon Poh Keong and Song Zuowen, a Chinese billionaire, are increasing their investments in aluminum ventures through strategic stake swap. Furthermore, aluminum stocks are giving a return of 4.32%, year-to-date, surpassing the broader market’s -4.13% performance. Thus, these billionaire-backed entries reflect the industry’s strength and future potential.
With this, let’s now look into the 10 Best Aluminum Stocks To Buy According to Billionaires.
