Redefining the standard of aluminium purification
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.
