Manufacturers Face Crunch on Industrial Metals

Why It Matters

Higher aluminum costs threaten U.S. manufacturing competitiveness, especially in auto and aerospace, while supply‑chain shocks accelerate the push for domestic critical‑minerals capacity and broader diversification.

Key Takeaways

• US aluminum prices up ~90% since war began.
• Tariffs on aluminum rose from 10% to 50%, squeezing manufacturers.
• Auto sector consumes 30% more aluminum than in 2020, facing cost pressure.
• New US smelter slated for construction, first since 1980, to boost capacity.
• Copper demand projected to grow 50% by 2040, amid supply shortfall.

Pulse Analysis

The conflict in Iran has exposed the fragility of the industrial‑metals supply chain that underpins U.S. manufacturing. Aluminum, a cornerstone for everything from fighter jets to beverage cans, has seen its domestic price surge by almost 90% since the war began. The spike is driven by a combination of disrupted Gulf shipments and a dramatic tariff increase—from 10% to 50%—that squeezes margins for automakers and aerospace firms alike. As manufacturers scramble for alternatives, the price shock is prompting a reevaluation of sourcing strategies and cost‑pass‑through mechanisms.

For the auto sector, the timing is especially painful. U.S. vehicle makers have increased aluminum usage by 30% since 2020 to meet weight‑reduction targets, yet the soaring input costs erode profitability and threaten planned model rollouts. A silver lining emerges with the announcement of a new U.S. smelter, the first greenfield project in four decades, slated to break ground later this year. While the plant won’t be operational until the decade’s end, it signals a strategic shift toward domestic capacity. Meanwhile, Chinese output is expected to rise in the second half of 2024, potentially easing the global supply deficit that has persisted since 2019.

Looking beyond aluminum, the longer‑term outlook for industrial metals hinges on demand growth and geopolitical realignment. Copper demand is projected to climb 50% by 2040, fueled by renewable‑energy infrastructure and AI‑driven technologies, even as analysts warn of a production peak around 2030. The United States and the European Union are deepening cooperation on critical minerals, drafting standards for mining, processing, recycling, and even price floors. These initiatives aim to reduce reliance on China, which dominates the supply of lithium, rare‑earths, and tungsten. As oil‑linked mining costs rise and supply shocks persist, diversifying sources and bolstering domestic production become essential for maintaining industrial resilience.
