GLASSMATE®-GM Graphite

Strong and durable, this graphite material is ideal for precision processes with elevated wear rates such as thread pickup and long production runs where repeatability is paramount.

  • Average particle size of less than 3 microns provides high material strength and resistance to damage
  • Fine surface finish creates precision threads that meet tight tolerance process specifications
  • Improved wear-resistance characteristics extend product life, minimizing costly replacements and downtime

Our graphite grades are available as semi-finished rods, blocks, plates, and fully machined parts.
