Copper Alloy C12200 vs TU1
Copper Alloy · grade comparison
Copper Alloy C12200 and TU1 are both copper alloy grades. C12200 is the stronger of the two: yield strength 76 MPa (11 ksi) against 69 MPa (10 ksi) for TU1, about 10% more; tensile strength follows at 235 MPa (34.1 ksi) vs 221 MPa (32.1 ksi). TU1 runs hotter in service (250°C vs 200°C continuous) and TU1 conducts heat better (391 W/m·K vs 339 W/m·K). On the shop floor, C12200 welds better (excellent vs very good).
C12200Choose it when strength drives the design, or when it will be welded.
TU1Choose it when the part sees heat.
C12200 vs TU1: 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.

C12200 vs TU1 — frequently asked
Is C12200 stronger than TU1?
Yes. C12200 has a typical yield strength of 76 MPa (11 ksi) against 69 MPa (10 ksi) for TU1 — about 10% more. Tensile strength is 235 MPa (34.1 ksi) vs 221 MPa (32.1 ksi).
Which is cheaper, C12200 or TU1?
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, C12200 or TU1?
TU1, 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 TU1 (very good, 70/100).
