Canada’s aluminum sector is set for a strong 2026, driven by global demand for low-carbon materials. As the world’s fourth-largest primary aluminum producer, Canada benefits from a critical advantage: nearly 96% of its smelting is powered by clean hydroelectricity, giving it the lowest carbon footprint among major producers.
This “green aluminum” status is increasingly vital for the Electric Vehicle (EV) and renewable energy sectors, which depend on aluminum’s light weight. The market is robust, with the Canadian aluminum extrusion market projected to grow at a CAGR of 7.5% from 2025 to 2030. Strategic government support and the sector’s crucial role in North American supply chains further underpin its stability.
While challenges like global price volatility and trade uncertainties persist, the foundational trend is clear: Canada is uniquely positioned to capitalize on the shift to sustainable metals. This article explores the top Canadian aluminum companies best positioned to leverage the green metal advantage for significant returns.
Below we’ll break down aluminum stocks and help you decide if you should invest in this versatile metal.
What are aluminum stocks?
Aluminum stocks are companies involved in mining, manufacturing, and reshaping aluminum into everyday products.
Unlike other raw materials, pure aluminum doesn’t occur naturally. Rather, it’s an element that’s found within two minerals: bauxite and cyolite. To extract it, many aluminum companies will mine and refine bauxite, then smelt it down to isolate pure aluminum. They’ll then add alloys — such as copper, silicon, zinc, and tin — to make aluminum stronger.
It takes immense amounts of labor — and electricity — to manufacture aluminum. But it’s well worth the effort. Aluminum is not only durable but lightweight. This makes it useful for the aerospace and airline industries, which require strong metals that are featherlight to improve lift and decrease drag. It’s also ideal for automakers, especially electric vehicle companies, as lighter cars mean greater fuel economy.
But aluminum isn’t limited to vehicles and airlines. As the second most malleable metal in the world, it’s a basic ingredient in many everyday products, including:
- Kitchen utensils and foils
- Food packaging and cans
- Power lines
- Consumer electronics, such as laptops, phones, and tablets
- Window frames and doors
- Household and industrial appliances
- Construction materials, such as pipes, bars, wires, pins, railings, shutters, tubing, sheets, and casts.
These various uses of aluminum have given aluminum companies a strong foundation on which to operate. Plus, demand for aluminum in both Canada and the U.S. continues to trend upwards.(1) This is spurred by both consumer demand for products that are recyclable, and battery-powered vehicles and other energy industry uses.
Top aluminum stocks
Many of the top aluminum stocks are headquartered in the U.S. and elsewhere in the world. Below we’ll discuss some of the best aluminum stocks on the world market.
| Aluminum Stocks | Description |
| Rio Tinto (NYSE:RIO) | Diversified mining company with five bauxite mines, four alumina refineries, and 14 smelters |
| Alcoa (NYSE:AA) | Major aluminum producer in North America and one of the world’s largest miners of bauxite |
| Cymat Technologies Ltd (TSX-V: CYM) | Canadian materials technology company that manufactures and sells Stabilized Aluminum Foam (SAF) |
Rio Tinto
Headquartered in both London and Melbourne, Rio Tinto is the world’s second largest metal and mining company. With operations in 35 countries, they mine for numerous raw materials, including copper, iron ore, uranium, diamonds, and bauxite. Rio Tinto acquired Arcadium Lithium for $6.7 billion in late 2024, aiming to strengthen its position as a leading lithium supplier.
As an integrated aluminum producer, Rio Tinto operates 5 bauxite mines, 4 alumina refineries, and 14 smelters. The company recently received positive headlines in Canada for decarbonizing smelters and vowing to reduce greenhouse gases by 50% before 2030.
While the company plays a vital role in the aluminum industry, aluminum isn’t Rio Tinto’s biggest venture. In fact, aluminum makes up a small part of its revenue: roughly 9%.
That’s not a bad thing, however. In fact, in the cyclical mining industry, mining companies that diversify their operations are better protected when demand for one mineral falls. But for investors looking for a pure aluminum company, you might want to consider the other stocks below.
Alcoa
Headquartered in Pittsburgh, Pennsylvania, Alcoa is one of the largest integrated aluminum producers in the world. They operate in 10 countries and have facilities in Brazil, Spain, Australia, the United States, Guinea, and Suriname.
For the full year 2025, the company projects Alumina segment production between 9.5 and 9.7 million metric tons, with higher shipments (13.1 to 13.3 million metric tons) supported by trading.
Much of Alcoa’s smelters run on renewable energy—around 87%. This is impressive, as smelters require immense amounts of electricity. Alcoa has also partnered with Rio Tinto to create ELYSIS, a groundbreaking initiative focused on developing zero-carbon aluminum production technology. Supported by investments from Apple, the governments of Canada and Quebec, and other stakeholders, ELYSIS represents a significant step toward sustainable aluminum production and aligns with global efforts to reduce industrial carbon emissions.
Cymat Technologies
Cymat Technologies (TSX-V: CYM) is an innovative materials technology company based in Mississauga, Ontario. As a key player in the downstream, high-value specialty materials segment Cymat holds global patents for Stabilized Aluminum Foam (SAF), marketed as Alusion™ (architecture) and SmartMetal™ (automotive/defense).
The company saw significant commercial growth in 2024-2025, achieving record Q1 fiscal 2025 revenue of $2 million and positive cash flow, largely driven by its architectural business, including a major order for the NEOM development in Saudi Arabia. The SmartMetal™ division secured its first serial production military order for underbelly blast protection in mid-2024 and a significant $2.7 million order for nuclear facility protection panels in late 2024.
Cymat also expanded its automotive focus in 2025 by entering a strategic partnership with a Tier 1 manufacturer for lightweight components and securing a Joint Development Agreement with a major Japanese firm to develop lightweight EV battery encasements, demonstrating a strong move toward high-value, predictable, contractual revenue.
Are aluminum stocks right for you?
Aluminum is a key ingredient in many products we’ve come to depend on. Additionally, there are numerous emerging markets — such as electric vehicles and renewable energy — that require aluminum. All in all, the high demand for aluminum makes a compelling case to have some exposure to the companies that manufacture it.
Before you invest in aluminum, however, you should know that aluminum stocks are considered cyclical. In other words, these companies will generate more revenue and enjoy higher valuations in strong economies versus weak ones. If the overall economy slows down, consumers will generally have less income to spend. That could reduce demand for many of the products that use aluminum. This reduction in demand trickles down to the aluminum companies themselves, which may lay off workers or close mines to reduce operational costs.
That shouldn’t stop you from investing in aluminum companies. But it might make you more cautious about how much exposure you have to cyclical stocks (like airlines, retail stores, industrials, and other raw materials). If you already have a large holding in cyclical stocks, you might want to invest in income or safe stocks to balance yourself out.
For broad exposure to the aluminum market, you might want to invest in an aluminum-focused ETF. An exchange-traded fund (ETF) will spread your investment money among numerous companies, helping you diversify.
Some aluminum ETFs include:
- iShares U.S. Basic Materials ETF (IYM)
- iPath Series B Bloomberg Aluminum Subindex Total Return ETN (JJU)
