Alcoa Corp., a leading aluminum producer in the US, announced last Friday (July 1) that it decided to instantly entirely curtail the operation at one of three smelting lines at its Warrick Smelter in Indiana due to operational challenges.

The annual production capacity of each of the three smelting lines at the Warrick facility is around 54,000 tons. The total yearly nameplate capacity at the Warrick Smelter's five potlines is 269,000 tons.

Alcoa said that it will ensure the safe capacity curtailment and protect the operation at the two other lines.
