Lightweight metals leader Alcoa (NYSE:AA) today announced it will delay
the curtailment of its Intalco Works smelter in Ferndale, Washington
until the end of the second quarter of 2016. The plant was initially
scheduled to curtail by the end of the first quarter.

The Company announced a full curtailment of the Intalco smelter (230kmt)
on November 2, 2015, with the plant’s casthouse continuing to operate.
However, recent changes in energy and raw material costs have made it
more cost effective in the near term to keep the smelter operating to
provide molten metal to the plant’s casthouse.

Once all announced curtailments and closures are complete, the Company
will have removed approximately 25 percent operating smelting capacity
and approximately 20 percent of operating refining capacity by mid-2016,
and Alcoa globally will have 2.1 million metric tons of operating
smelting capacity and 12.3 million metric tons of operating refining
capacity remaining.
