As the United States celebrates 250 years of independence, it’s a moment to reflect on the industries that have powered its journey from a fledgling nation to a global economic powerhouse. Among them, aluminium stands out as a quiet yet indispensable force driving innovation, employment, and sustainability. From building iconic infrastructure to enabling advanced manufacturing and clean energy solutions, aluminium has been at the heart of America’s economic transformation.
The aluminium industry today serves as a cornerstone of the US economy, contributing significantly to employment, industrial output, tax revenues, and supporting crucial value chains. According to a 2024 study by John Dunham & Associates for the Aluminum Association, the US aluminium sector directly employs 164,140 workers, while indirectly and through induced effects supports a total of approximately 699,959 jobs nationwide.
These roles aren’t merely desk jobs; workers in aluminium production earn about USD13.96 billion in wages and benefits, while their indirect and induced positions contribute another USD. When employees spend their incomes in local economies, on housing, services and goods, this “multiplier effect” generates an additional 271,974 jobs and contributes USD 57.60 billion in economic activity.
Massive economic output & tax contribution
Altogether, the US aluminium industry delivers a total economic output of USD 228.31 billion, equivalent to roughly 1.02 per cent of US GDP. This includes USD 92 billion in direct output and USD 136 billion in output via secondary (indirect) channels. The sector is also responsible for USD 22.74 billion in federal, state, and local tax revenues, a substantial injection of public funds.
A pivot from primary smelting to recycling and downstream manufacturing
Since 2013, although primary smelter jobs have declined by nearly 70 per cent, jobs in mid- and downstream sectors, like recycling, coatings, extrusion, sheet and plate, have not only remained stable but have shown steady growth. Between 2022 and 2024, jobs in secondary aluminium production and recycling rose by 12.5 per cent, aluminium coatings by 9.6 per cent, and sheet & plate manufacturing increased by 6 per cent. These segments now make up around 98 per cent of all US aluminium sector employment.
The industry has committed over USD 10 billion to domestic fabrication, recycling facilities and the first greenfield rolling mills in decades, alongside more than USD 650 million in Department of Energy grants to support decarbonisation. The result is a cleaner, more sustainable production model and a more resilient manufacturing ecosystem.
Competitive challenges
However, the sector’s future depends heavily on two factors: access to affordable electricity and fair trade policies. A Financial Times analysis noted that U.S. smelters are hampered by electricity rates nearly double those in Canada, undermining global competitiveness. As of March 2025, US aluminium import tariffs were raised to 25 per cent and then 50 per cent, to protect domestic production, a move with mixed results, given persistent energy cost disadvantages.
Strategic value
Beyond employment and fiscal returns, the shift toward recycling has clear environmental benefits. Secondary production uses only around 10 per cent the energy of primary smelting. This not only reduces emissions but positions the US industry at the forefront of the circular economy.
The path forward
To fully capitalise on its economic importance, the US aluminium industry advocates for:
- Energy incentives: Access to low-cost renewable power to offset energy intensity.
- Targeted trade enforcement: To counter subsidised global imports and maintain domestic smelter viability.
- Investment in innovation: Continued growth in recycling, smart fabrication, and sustainable tech through federal programmes.
Conclusion
The US aluminium industry is an economic juggernaut, employing nearly 700,000 people, delivering over USD 228 billion in output, and generating substantial tax revenues. While primary smelting faces structural challenges, especially energy costs and global competition, the industry’s pivot to recycling and downstream manufacturing has strengthened its resilience and sustainability. With supportive policies, be it energy subsidies, trade protections, or R&D funding, the sector is poised to remain a strategic driver of American industrial and economic leadership.
