Alcoa

The Pittsburgh company that commercialised the Hall–Héroult smelting process, held a near-monopoly on US primary aluminium for half a century, became a management-school case for safety under Paul O'Neill, split itself in two in 2016 and is now a pure upstream producer of bauxite, alumina and primary aluminium whose profits depend on power contracts, the alumina price and where its smelters sit relative to US tariffs. Alcoa's manufacturing story turns on process capability as its founding edge, safety as the measure that rebuilt that capability, and power as the raw material that decides which smelters live. Its US smelting footprint shrank through decades of curtailments as power contracts expired; its Canadian smelters became a tariff question when Section 232 duties on aluminium went from 10% (23 Mar 2018) to 50% (4 Jun 2025) (Shared facts). In 2024 it bought out its Australian partner Alumina Ltd; on 30 Jun 2026 it agreed to buy South32's bauxite, alumina and aluminium assets ("AliGroup") for ~$4.1bn upfront — not closed at early Nov 2026.
