GLASSMATE®-XL Graphite

Our premium graphite material offers a tighter microstructure and the highest hardness in the GLASSMATE® portfolio to improve wear resistance and glass surface quality. 

  • Average particle size of less than 1 micron provides premiere material strength and resistance to damage
  • Increased material strength resists deformation caused during rigorous manufacturing
  • 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.
