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.
