OUR
COMPANY
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, Direct Lithium Extraction (DLE) technology and lithium-ion battery industries, but what sets us apart is our market-leading purity levels, developed with a dramatically lower carbon profile.
