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.
Alpha HPA is on a mission to supply decarbonisation by delivering the most sustainable, high purity aluminium products to the world. Our use of the Smart SX Technology reflects our commitment to global decarbonisation and our vision to bring the entire world forward, together.
We’re driven to leave a positive legacy for generations to come – we’re a team of collaborators and hard workers who look out for one another, and this includes taking care of our world.
