Bahrain’s Alba shuts 19% of aluminum capacity as Hormuz disruption continues

Aluminium Bahrain, known as Alba, said on Sunday it had initiated a shutdown of three aluminum smelting lines accounting for 19% of its capacity to preserve business continuity amid ongoing disruption in the Strait of Hormuz.

The closures are the latest impact on the Middle East aluminum sector, which accounts for around 9% of global supply, from the US-Israeli war on Iran. Fears of shortages propelled London Metal Exchange aluminum to a nearly four-year high of $3,546.50 per metric ton on Thursday.

Alba, which has smelting capacity of 1.62 million tons of aluminum per year, said in a statement it had initiated a “controlled and safe shutdown” of reduction lines 1, 2 and 3.

“This targeted, line-specific action is designed to optimize the utilization of Alba’s existing raw materials inventory and prioritize operational stability across Reduction Lines 4, 5 and 6,” added Alba, which describes itself as the “world’s largest aluminum smelter on one site.”

The company had issued force majeure on March 4 since it was unable to ship metal to customers due to the effective closure of the Strait of Hormuz. The closure has also left Middle East smelters unable to bring in vessels carrying their key raw material, alumina.

Energy supply is another issue for smelters. Qatar’s Qatalum had begun a shutdown on March 3 due to a suspension of its gas supply but will now operate at 60% capacity.

Alba, meanwhile, said it would use the opportunity to undertake asset care and maintenance on the three shuttered lines, including comprehensive housekeeping and cleaning activities, laying the foundations for a safe restart when conditions improve.

“The company is also working closely with suppliers and customers to manage commitments and mitigate disruption,” it added.
