Unionized workers at Aurubis Buffalo's brass and copper plant in North Buffalo approved a three-year contract.
Members of United Steelworkers Local 593 ratified the deal on Feb. 22, more than a month before the previous contract's March 31 expiration date. The new deal, which covers about 500 production and maintenance workers, is set to expire in March 2020.
Terms of the deal were not disclosed.
"Both management and the union expressed an interest in beginning discussions earlier than previously done so in order that key issues and matters could be discussed and resolved before a looming strike deadline.," the company said in a statement.
The company in a statement said the union and management "wanted to send a signal" to customers, suppliers and the copper and brass market that the company would remain stable.
The Aurubis plant has operated under different names over the years, including American Brass, Outokumpu and Luvata. Germany-based Aurubis bought the facility in 2011 as part of a larger deal.
