C10800 vs C12200: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy 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.

C10800 vs C12200 — frequently asked
Is C12200 stronger than C10800?
Yes. C12200 has a typical yield strength of 76 MPa (11 ksi) against 69 MPa (10 ksi) for C10800 — about 10% more. Tensile strength is 235 MPa (34.1 ksi) vs 221 MPa (32.1 ksi).
Which is cheaper, C10800 or C12200?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C10800 or C12200?
C10800, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for C12200; for welding the order is C12200 first (excellent, 85/100) then C10800 (very good, 80/100).
