Ms Brock will succeed Steve Larkin, who has served as the Association’s president since 1998, and earlier this year announced his plan to retire at the end of 2011.
Steve Demetriou, Aleris chairman and ceo of the Aluminum Association said: “The Aluminum Association and our staff have accomplished a great deal under Steve Larkin’s leadership during the past 13 years as he successfully led the Association through the most challenging time in the industry’s history.
"I am certain that Heidi’s skills, experience and drive will ensure continued success in the years to come as we take the industry’s sustainability message to the next level. “
Ms Brock served most recently as vice president of Federal and International Affairs for the Weyerhaeuser Company.
She is currently a member of the executive committee and board of both the National Institute of Building Sciences and the US-Japan Leadership Programme. She was previously Weyerhaeuser’s e-business vice president.
Ms Brock has a BA from the University of Puget Sound and an MBA from Georgetown University.
