Alpha HPA says demand for its high-purity aluminium materials has moved ahead of planned output from its Gladstone facility, driven by rapid expansion in artificial intelligence infrastructure, semiconductor manufacturing and battery production.
The Australian company, listed on the ASX, is developing what it describes as the world’s largest single-site facility for high-purity aluminium materials in Queensland. It has now secured Letters of Intent covering more than 12,000 tonnes of annual product demand, above the Stage Two planned capacity of 10,430 tonnes per year.
Recent commitments include customers in South Korea’s semiconductor supply chain, a global specialty materials producer and a lithium-ion battery materials manufacturer.
Managing Director Rob Williamson said demand growth reflects the increasing technical requirements of advanced electronics and energy systems.
“The global build-out of AI infrastructure is creating enormous demand for these specialised materials that help semiconductors run faster, cooler and more efficiently,” he said.
“As artificial intelligence systems become more powerful, the chips that power them generate more heat. Our materials are increasingly being used to improve thermal management, semiconductor packaging and manufacturing processes that are essential to the next generation of AI technology.”
A new Letter of Intent includes supply of up to 300 tonnes a year of high-purity alumina products for semiconductor thermal fillers, designed to help manage heat in AI servers and data centre chips.
Another agreement covers up to 180 tonnes annually of high-purity alumina hydrate for catalyst applications, while a third commitment relates to up to 5,000 tonnes a year of high-purity aluminium materials for advanced lithium-ion batteries.
Mr Williamson said global investment in AI infrastructure is reshaping demand patterns across the materials sector.
“The scale of investment flowing into AI infrastructure globally is creating demand for specialised materials that simply weren’t required a decade ago. What we’re seeing now is customers looking to secure long-term supply of these materials as semiconductor production expands,” he said.
He said requirements from manufacturers are becoming more precise, particularly around purity levels needed for advanced chips.
“Our customers are increasingly seeking ultra-high purity materials with extremely low levels of uranium and thorium impurities. These impurities emit alpha radiation that interferes with advanced semiconductors. Our process technology allows us to produce the lowest alpha-radiation materials available anywhere in the world,” he said.
Alpha HPA is currently producing commercial quantities at its Stage One facility in Gladstone while construction continues on Stage Two, which is expected to be completed late next year.
The company said it is also receiving increased interest from semiconductor manufacturers looking to diversify supply chains, with recent engagement across the United States, Japan, South Korea, Taiwan and Europe.
Beyond semiconductors, its materials are used in battery technologies, direct lithium extraction, ceramics, synthetic sapphire glass, catalysts and pharmaceutical applications.
Alpha HPA said its purification process produces high-purity aluminium materials with lower carbon emissions compared with conventional methods, positioning Australia within a growing global supply chain for critical technology materials.
With demand commitments now exceeding planned Stage Two capacity, the company said it is assessing further expansion options beyond its current development program.

Support Independent Community Journalism
Dear Reader,The Indian Sun exists for one reason: to tell stories that might otherwise go unheard.
We report on local councils, state politics, small businesses and cultural festivals. We focus on the Indian diaspora and the wider multicultural community with care, balance and accountability. We publish in print and online, send regular newsletters and produce video content. We also run media training programs to help community organisations share their own stories.
We operate independently.
Community journalism does not have the backing of large media corporations. Advertising revenue fluctuates. Platform algorithms change. Costs continue to rise. Yet the need for credible, grounded reporting in a multicultural Australia has never been greater.
When you support The Indian Sun, you support:
• Independent reporting on issues affecting migrant communities
• Coverage of local and state decisions that shape daily life
• A platform for small businesses and community groups
• Media training that builds skills within the community
• Journalism accountable to readers
We cannot cover everything, but we work to cover what matters.
If you value thoughtful reporting that reflects Australia’s diversity, we invite you to contribute. Every donation helps us maintain the quality and consistency of our work.
