Production Chart – Aluminium
Aluminium
ALUMINIUM S.A. produces primary cast aluminium through the electrolysis of calcined (anhydrous) alumina. Primary cast aluminium is then processed to obtain
the aluminium end products (billets, slabs and T-ingots).
Client satisfaction
The difficult conditions in the aluminium sector and the negative economic climate in Greece prevented the Company from conducting a more thorough client
satisfaction survey. Nevertheless, the relevant annual survey was carried out with 17 clients (5 in Greece and 12 abroad). Response to the survey by the
Company’s clients was 53%. The table below lists the subjects covered by this survey and the Company’s performance in each one of them together with its
