CHICAGO — A fire at Alcoa Inc.’s Howmet Alloy Operations in Dover, N.J., has been extinguished, the company told AMM Feb. 22.

Alcoa put out the “small” fire that broke out on the morning of Feb. 22 and is investigating its cause, a spokeswoman for the Pittsburgh-based aluminum producer said in an e-mail to AMM.

Fire departments in Rockaway Township, Rockaway Borough and Dover Township, all of New Jersey, also responded to the blaze, the spokeswoman said.

There were no injuries, and operations have returned to normal, according to the spokeswoman.

The Howmet plant supplies nickel- and cobalt-based superalloys to several markets, including the aerospace, medical and industrial sectors, according to Alcoa’s website.
