Aluminium Norf GmbH was founded in April 1965 by former Alcan (now: Novelis) and former VAW (now Hydro Aluminium) as a joint venture. This joint venture in Norf near the city of Neuss created the then biggest aluminium rolling and remelt plant in Europe, setting new standards for the processing of aluminium to sheet and plate for a wide range of applications. To meet the demand for even higher quality and ever increasing production volume Aluminium Norf GmbH has undergone considerable expansion and modernisation since its foundation. With the biggest expansion between 1990 and 1994 Aluminium Norf GmbH – in short Alunorf – has become the world's largest aluminium rolling and remelt plant.
The area of Aluminium Norf GmbH encompasses 577,000 m² - this corresponds to the size of 60 soccer fields. 285,000 m² thereof are used for buildings, 212,000 m² for roads and railway tracks. Alunorf's production comprises the three units aluminium melting, hot rolling and cold rolling. Auxiliary and service departments, e. g. energy supply, maintenance workshops and stores support the production units.
Alunorf employs more than 2,200 people; the production is organised in shift systems that allow operation around the clock, 7 days a week. The sales volume has continuously increased and now totals to approx. 1,500,000 tons per year.
