Alpha HPA is a publicly listed, Australian-based company which has commercialised the world’s first adoption of the solvent extraction (SX) purification technique to aluminium to produce a growing range of ultra-high purity aluminium materials. Our high purity aluminium oxides, hydroxides, nitrates and sulphates are found in a wide range of high technology industries including LED lighting, synthetic sapphire, semiconductors, and lithium-ion battery markets, but what sets us apart is our market-leading purity levels, developed with a dramatically lower carbon profile.
