Sgl Carbon SE
A German maker of carbon and graphite products, SGL Carbon produces graphite electrodes for steelmaking, carbon fibers for lightweight automotive and aerospace parts, and specialty graphite used in semiconductors and batteries. The company was born in 1992 from the merger of Germany's Sigri and the European operations of America's Great Lakes Carbon — the "SGL" in its name stands for "Sigri Great Lakes." Today its materials show up in everything from electric car bodies to the electrodes that power steel furnaces.
