EDM-AF5^® Graphite

Our EDM-AF5^® graphite is the premier Angstrofine graphite electrode material available on the market today with an average particle size of less than 1 micron. This gives this grade advanced properties that exceed those with larger particle sizes.

Average particle size of less than 1 micron provides superior strength and resistance to damage
Fine surface finish (7Ra) reduces imperfections, minimizing the introduction of defects into the mold
Excellent metal removal rate shortens production times allowing for higher production rates
High resistance to wear minimizing replacement needs and reduces cost of ownership

Available for order as billets, semi-finished rods, blocks, and plates.
