NEW YORK — Alcoa Inc. has appointed Eric Roegner to the newly created position of chief operating officer of Alcoa Investment Castings, Forgings & Extrusions.

Roegner had been president of Alcoa Forgings & Extrusions since 2009. He will be succeeded in that post by Jacques Vanier, who had been chief operating officer of forgings and extrusions since January 2012.

In his new role, Roegner will be responsible for Alcoa’s Power and Propulsion, Forgings and Extrusions, Oil and Gas, and Defense units, the company said, and also will serve on the Pittsburgh-based producer’s executive council. Roegner will continue to report to Olivier Jarrault, executive vice president and group president of Alcoa’s Engineered Products and Solutions business.

Both Vanier and Mike Pepper, president of Alcoa Power and Propulsion, will report to Roegner.

Roegner joined Alcoa in 2006 as chief operating officer of its global extruded products business.

Vanier rejoined Alcoa in 2010 as chief operating officer of the extrusions business and assumed operations responsibility for the forgings business in 2012. He previously was vice president of manufacturing at American Commercial Lines Inc.
