We are alpha hpa

At Alpha HPA, we are proud to be at the forefront of the global effort to decarbonise our world. We specialise in producing ultra-high purity alumina (HPA) and related premium aluminium materials through our proprietary solvent extraction (SX) and refining technology. Our process results in market-leading purity levels and a dramatically lower carbon profile.
Made in Australia; distributed globally. We are Alpha HPA.

Products that are driving innovation

Our ultra-high purity aluminium materials, including high purity alumina and high purity aluminium salts, are essential components in the production of LED lighting, synthetic sapphire, semiconductors, and lithium-ion batteries. As these markets continue to grow rapidly, we are committed to meeting the increasing demand with our innovative technology and expanding production capacity.
