“North America’s aluminum sector in 2026 features limited but resilient primary smelting capacity in the US, bolstered by Canada’s robust operations, heavy reliance on imports for raw materials like bauxite and alumina, and growing secondary recycling. Major players include Alcoa, Century Aluminum, Novelis, and Rio Tinto, with emerging projects signaling potential capacity expansion amid high energy costs and trade tensions.”
North American Aluminum Ecosystem: Producers, Traders, and Suppliers in Focus
The North American aluminum industry remains a cornerstone of manufacturing, supporting transportation (36% of consumption), packaging (23%), building (14%), electrical (9%), and other sectors. Primary production faces structural challenges, with the US operating at reduced capacity due to high energy costs and historical closures, while Canada maintains near-full utilization thanks to abundant hydroelectric power.
In the US, primary aluminum production hovers around 670,000 metric tons annually from four operational smelters, down from historical peaks. Key facilities include:
Alcoa Corporation operates smelters in Massena, New York (capacity ~130,000 tons per year, powered by renewable hydro), and Warrick, Indiana. Alcoa focuses on integrated operations, including upstream bauxite and alumina, with recent investments in modernization like a $60 million anode baking furnace upgrade at Massena.
Century Aluminum Company runs the Sebree smelter in Kentucky ( 220,000 tons capacity) and Mount Holly in South Carolina ( 229,000 tons full capacity, previously at ~75%). Century announced a $50 million restart of idled lines at Mount Holly, targeting full capacity by mid-2026, potentially boosting US output by about 10%.
Secondary aluminum, derived from scrap, dominates supply, contributing over 75% of domestic needs and growing with recycling emphasis. Apparent consumption stands around 4.3 million tons, with net import reliance at ~47%.
Canada produces over 3 million tons annually from multiple smelters, primarily in Quebec, operated by companies like Rio Tinto (majority owner of several facilities using hydro power), Aluminerie Alouette, and Alcoa (with Canadian operations). Canadian output supports US demand significantly, though recent retaliatory tariffs complicate cross-border flows.
Major North American Players in Aluminum Production and Processing
| Company | Key Operations | Focus Areas | Notable 2026 Developments |
|---|---|---|---|
| Alcoa Corporation | US smelters (Massena, Warrick); Canadian assets | Integrated bauxite, alumina, primary aluminum | Modernization investments; renewable energy emphasis |
| Century Aluminum | Sebree (KY), Mount Holly (SC) | Primary aluminum smelting | Mount Holly restart to full capacity mid-2026 |
| Novelis Inc. | Multiple rolling mills across NA | Downstream rolled products, recycling | Leading in automotive and packaging sheet |
| Rio Tinto | Canadian smelters; global bauxite/alumina | Primary production, low-carbon aluminum | Strong North American presence via hydro-powered facilities |
| Arconic | Davenport (IA) and other sites | High-purity aluminum for aerospace/defense | $57.5 million expansion for high-purity production |
| Norsk Hydro ASA | Extrusions and recycling facilities | Extrusions, sustainable aluminum | Expanding recycled billet capacity in NA |
| Kaiser Aluminum | Value-added plate, sheet, extrusions | Aerospace, automotive | High-value products for lightweighting |
Traders and suppliers play a critical role in bridging supply gaps. The US imports substantial volumes of primary aluminum, alumina, and bauxite, with Canada supplying the majority (~56% of imports historically). Other sources include the UAE, Bahrain, and scattered global suppliers. Traders facilitate spot and long-term contracts, often dealing in P1020 ingot, billet, and scrap.
Key Traders and Suppliers
Reliance Steel & Aluminum Co. operates extensive service centers for distribution.
Tri-Arrows Aluminum and South32 handle alumina and bauxite sourcing.
Kloeckner Metals and others expand non-ferrous capabilities, including aluminum trading and processing.
Bauxite and alumina remain heavily imported, as North America lacks significant domestic mining. Global leaders like Rio Tinto (Australia), Norsk Hydro, and others supply alumina refineries, with emerging interest in North American projects (e.g., potential Canadian alumina developments). Demand for low-carbon and recycled materials grows, driven by sustainability mandates.
Market Drivers and Challenges in 2026
Demand surges from AI data centers (requiring massive aluminum for infrastructure), EVs (lightweighting), renewables, and defense. North American aluminum market size approaches $35-40 billion, with CAGR around 4.6%.
Challenges include energy costs constraining US smelting, tariff impacts (e.g., 25% on imports affecting cross-border trade), and competition from China and Indonesia. Restart and greenfield projects offer hope: Emirates Global Aluminium (EGA) and Century Aluminum plan a major new smelter in Inola, Oklahoma (~750,000 tons capacity), potentially the first new US primary facility in decades, with construction eyed for late 2026 and production by decade’s end.
The ecosystem emphasizes resilience through recycling (secondary production rising), trusted partnerships (especially Canada-US integration), and policy support for domestic revival.
