Alumina

Alumina is a white, crystalline form of aluminum oxide with a sand-like consistency. We are the world’s largest third-party producer.

Most of the alumina we produce is smelter-grade, used to make aluminum metal. We also produce what’s known as non-metallurgical alumina, sold for a variety of industrial applications such as water purification and creation of refractory.

World leadership in production and sustainability.


  • World’s first and only low-carbon alumina brand, EcoSource?.
  • Installed capacity: 17 million metric tons/year.
  • Six refineries in Australia, Brazil and Spain.
  • Our three-refinery operation in Western Australia is the world's biggest single source of alumina, able to supply eight percent of the global market.
  • 25% share in the refinery that is part of our Ma’aden joint venture in Saudi Arabia.

Leadership in cleaner, more efficient refining.

Technology developed by our Refining Center of Excellence in Australia over the prior decade has steadily increased our system-wide capacity by the equivalent of a new refinery without greenfield development.

Advanced technologies such as Mechanical Vapor Recompression (MVR), currently being tested in Australia, are helping maintain our lead in low-carbon refining. In addition, Alcoa refineries have led the way in ISO9001 and ISO14001 certifications for quality and environmental performance.

We sell more than half our production externally.
