Poco Graphite TRA Semiconductor Grade Graphite  (discontinued **)
Categories: Carbon; Graphite

Material Notes: Although it is impossible to identify differences between various grades of graphite by looking at them, each grade has a special set of characteristics and physical properties that determine their performance under specific conditions. The manufacturing process for each grade is tightly controlled to produce materials that have a uniform microstructure and the right balance of strength, grain size and hardness to offer optimum performance for their intended applications.
