Australia, Japan, the United States and Alcoa Announce Final Investment Decision for Gallium Project in Western Australia

Key Terms

gallium technical

Gallium is a soft, silvery metal used as a key ingredient in advanced electronic materials that power LEDs, high-speed computer and communications chips, and next‑generation power devices. Investors care because gallium’s supply is limited and concentrated in a few sources, so shortages or price swings can raise production costs and disrupt companies that depend on it—similar to how a bakery would be affected if flour became scarce or expensive.

semiconductors technical

Materials and the electronic components made from them that control the flow of electricity inside devices, enabling functions like computing, sensing, and communication; think of them as the traffic controllers that let electrical signals move where they’re needed. They matter to investors because semiconductors are core to virtually all modern technology—changes in demand, production capacity, or supply chains can quickly affect the revenues and stock values of many companies across industries.

defense applications technical

Uses of products, technologies, or services specifically designed for military, national security, or defense-related missions—such as weapons systems, surveillance gear, secure communications, cyber tools, or logistics support. For investors, defense applications matter because they can change a company’s revenue mix, expose it to government contracting rules, export controls, long procurement cycles and political scrutiny, much like selling specialized tools to a single large customer with strict rules.

critical mineral technical

A critical mineral is a naturally occurring element or metal that is essential for modern technologies—like batteries, electronics, clean energy systems and defense—and whose supply is vulnerable to disruption. Investors care because these minerals act like key building blocks: shortages, geopolitical controls, or production bottlenecks can sharply raise costs, stall product rollouts, change profit forecasts, and prompt government policy or subsidies that affect company valuations.

PITTSBURGH--(BUSINESS WIRE)-- The governments and industry partners of Australia, Japan and the United States, together with Alcoa Corporation (NYSE: AA; ASX: AAI) (“Alcoa”), announced that they have reached final investment decision for a gallium production plant to be co‑located at Alcoa’s Wagerup alumina refinery in Western Australia.

The gallium plant will be constructed and operated by Alcoa, leveraging the Company’s longstanding experience in alumina refining and advanced mineral processing. The facility will create a new, reliable source of gallium to support partner governments’ efforts to strengthen critical mineral supply chains.

“This final investment decision reflects a shared commitment by governments and industry to strengthen critical mineral supply chains among the partners,” said William F. Oplinger, President and Chief Executive Officer of Alcoa. “The project underscores the strategic importance of Western Australia and the role Alcoa’s operations play in delivering critical materials essential to the global economy.”

Gallium is a critical mineral used in advanced technologies, including semiconductors and defense applications, and global supply is currently highly concentrated. This project represents a collaborative effort to diversify supply and enhance resilience across key industries.

Construction activities are expected to commence following final site preparations. Alcoa’s participation in the joint venture, including its role as construction and operating manager, is not expected to have a material impact on the Company’s financial position or results of operations.
