Company history

GrafTech’s business was founded in 1886 as the National Carbon Company
National Carbon Company
The National Carbon Company was founded in 1886 by the former Brush Electric Company executive W. H. Lawrence, in association with Myron T. Herrick, James Parmelee, and Webb Hayes, son of U.S. President Rutherford B. Hayes, in Cleveland, Ohio. In 1890, National Carbon merged with Thomson-Houston,...

 in 1917, and the business that would later become GrafTech began to operate as the Carbon Products Division of Union Carbide.

Union Carbide was reorganized in 1989, with the Carbon Products Division renamed as the UCAR Carbon Company. In 2002, the company was rebranded as GrafTech International Ltd., and in 2008, became GrafTech International Holdings, Inc.

In late 2010, GrafTech acquired two companies: Seadrift Coke LP, a manufacturer of needle coke, which is an essential component in the production of graphite electrodes; and C/G Electrodes LLC, which manufactures graphite electrodes.

In February 2011, the company acquired Micron Research Corporation, a manufacturer of superfine-grained graphite.
