Our Graphite Materials Division, located in St. Mary’s, PA, has been producing carbon and graphite products for almost 100 years and EDM graphite for more than 50 years. The talented St. Mary’s engineering and manufacturing team have both the experience and expertise required to help you solve any EDM graphite challenge.
