Working with G10-ESD G11-ESD
Is G10-ESD easy to machine?
Machine dry with carbide or PCD tooling, high speed / moderate feed, sharp edges and rigid clamping; extract the abrasive glass dust and expect tool life well below that of plastics.
Can G10-ESD be welded?
Not weldable — thermoset laminate; join by bonding with epoxy/acrylic structural adhesive or by mechanical fasteners with washers to spread load.
Can G10-ESD be formed, bent or molded?
Supplied fully cured as flat sheet, rod or tube; no post-forming possible, so all geometry comes from machining, waterjetting or punching (thin sheet only, heated punch).
What surface finishes work on G10-ESD?
Edges should be deburred and sealed with epoxy to limit moisture wicking; no plating or anodizing — for coated antistatic grades avoid sanding or solvent wiping the functional surface.
G10-ESD chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What is G10-ESD G11-ESD used for?
G10-ESD G11-ESD is typically used for ESD assembly jigs, PCB test and probe fixtures, board-handling nests and locating plates, insulating standoffs in electronics test rigs, static-safe magazine rails and guides and machine tooling and mounting plates. In short: static-dissipative G10.
What is the tensile strength of G10-ESD G11-ESD?
G10-ESD G11-ESD has a typical tensile strength of 310 MPa (45 ksi) — stronger than 56% of composite grades. Strength varies by condition: see the 5 listed tempers.
Is G10-ESD G11-ESD easy to machine?
Not especially — machinability is rated fair (35/100, better than 50% of composite grades). Machine dry with carbide or PCD tooling, high speed / moderate feed, sharp edges and rigid clamping; extract the abrasive glass dust and expect tool life well below that of plastics.
Can G10-ESD G11-ESD be welded?
Not readily — weldability is rated not recommended (0/100). Not weldable — thermoset laminate; join by bonding with epoxy/acrylic structural adhesive or by mechanical fasteners with washers to spread load.
