Operations at Alcoa’s Portovesme, Italy, as well as La Coruña and Avilés, in Spain, will stop in H1 this year.
Alcoa said the facilities were among its highest-cost producers.
Last week, Alcoa announced the permanent closure of its smelter in Alcoa, Tennessee, and two potlines at its Rockdale, Texas, smelter.
The 150kt/y Portovesme site will be closed permanently while the La Coruña and Avilés curtailments are planned to be temporary. An uncompetitive energy position, combined with rising raw material costs and falling aluminium prices, led to the Alcoa decision.
The cutbacks at the three sites represent 240kt or 5% of Alcoa’s its global smelting capacity. About 1500 people are employed at the three sites.
Capacity at La Coruña and Avilés is 87kt/y and 93kt/y respectively.
