US backs Alcoa gallium plant with $243 million investment
The US government is investing $243 million to support Alcoa's (AA) new gallium plant in Australia, aiming to diversify supply chains for defense and tech industries. Gallium is crucial for semiconductors in advanced military systems. China dominates global production, prompting US efforts to secure alternative sources. The plant, part of a multinational partnership, will produce 100 tonnes of gallium annually once operational.
