A Berks County-based specialty metals company is growing again in Alabama.

Carpenter Technology Corporation, headquartered in Spring Township, announced plans Tuesday to build a superalloy powder plant near Athens.

The plant will be located directly across the street from Carpenter's new $518 million plant.

"Alabama is proving to be an excellent region for us," said William A. Wulfsohn, Carpenter's president & CEO. "There were several reasons why we selected Athens two years ago, including the location being ideal for future growth and expansion. We also remain extremely impressed with our access to a strong pool of skilled workers."

Work on the first plant is almost done, and officials said the new plant should be up and running in late 2015. With the addition of the new plant, Carpenter said it expects its Athens operations will employ 250 people by 2017.

Carpenter said it also expects to see substantial growth as aircraft engine technology improves.
