G10 vs G10-ESD
Composite · grade comparison
G10 and G10-ESD are both composite grades. G10 conducts heat better (0.35 W/m·K vs 0.3 W/m·K).
G10 vs G10-ESD: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

G10 vs G10-ESD — frequently asked
What is the difference between G10 and G10-ESD?
G10 and G10-ESD are both composite grades. G10 conducts heat better (0.35 W/m·K vs 0.3 W/m·K).
Which is cheaper, G10 or G10-ESD?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, G10 or G10-ESD?
G10, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for G10-ESD.
