ULTRA-HIGH PURITY ALUMINAS FOR ADVANCED TECHNOLOGIES
ALPHA HPA
ADVANCED MATERIALS MANUFACTURING
Alpha HPA is an advanced materials manufacturer specialising in ultra-high purity aluminas for demanding high-technology applications.
Our products support global supply chains across semiconductors, AI infrastructure, energy storage and advanced manufacturing, where purity and performance are critical.
We produce from Stage One of the HPA First Facility in Queensland, Australia, with Stage Two expanding our manufacturing capability to full commercial scale.
SMART SX TECHNOLOGY
THE TECHNOLOGY BEHIND OUR ADVANTAGE
Alpha HPA pioneered the world’s first application of solvent extraction to aluminium purification through our proprietary Smart SX Technology, creating a highly selective pathway to ultra-high purity materials.
Smart SX Technology enables the production of a growing range of high-purity materials with tightly controlled characteristics, while delivering a significantly lower carbon profile than conventional production routes.
OUR PRODUCT RANGE
A growing range of ultra-high purity aluminas and high-purity materials for different application requirements.
Our ability to control purity, particle characteristics and product form allows us to tailor materials for demanding applications across advanced technology markets.
