Hydro produces primary aluminium, or liquid aluminium, at Karmøy. Karmøy is one of Europe's largest primary aluminium plants and its energy supply comes from our hydropower plants in Røldal and Suldal.

There are two casthouses at Karmøy: one delivering extrusion ingot for profile production and one producing wire rod for high-voltage cables.

We also have a research and development center at the plant that focuses mainly on improving the production process.
