GRAPHITAR® is U.S. Graphite Inc.'s trade name for a family of carbon-graphite (mechanical carbon)products. U.S. Graphite traces its history back to 1891, when the company was formed to utilize a Mexican deposite of natural graphite. For over 100 years, USG has led in the development of mechanical carbons, from pencil "lead" to nuclear reactor components. GRAPHITAR® is made by blending powder allotropes of carbon, i.e. natural and artificial graphites, carbon blacks, petroleum cokes, etc. with a hydrocarbon binder, pressing this mix into shapes, then furnacing the shapes at over 2000oF. The resultant parts possess a unique combination of properties...lubricity, corrosion resistance, thermal stability, and wear resistance.
