Alcoa CorpAlcoa's final investment decision to build a gallium plant creates a new revenue stream from high-demand semiconductor and defense materials.

Alcoa, together with Australia, Japan, and the US, has confirmed a final investment decision to build a gallium production facility at its Wagerup alumina refinery in Western Australia. The plant will occupy about three hectares, less than 2% of the refinery's total area, and will process roughly 10% of its liquor stream without requiring additional bauxite mining. Construction is expected to create around 200 jobs and 20 operational roles, with Alcoa managing both construction and operation. The project aims to diversify highly concentrated global gallium supplies critical for semiconductors and defence applications. Alcoa president and CEO William Oplinger highlighted the strategic importance of Western Australia and the company's role in delivering critical materials to the global economy.
