Copper Alloy C16200 vs TU2
Copper Alloy · grade comparison
Copper Alloy C16200 and TU2 are both copper alloy grades. C16200 is the stronger of the two: yield strength 395 MPa (57.3 ksi) against 70 MPa (10.2 ksi) for TU2, about 5.6 times as much; tensile strength follows at 435 MPa (63.1 ksi) vs 230 MPa (33.4 ksi). In exchange, TU2 is the more ductile: elongation 45% versus 8% for C16200, and C16200 is harder (115 HB vs 42 HB). TU2 runs hotter in service (250°C vs 200°C continuous) and TU2 conducts heat better (391 W/m·K vs 350 W/m·K). On the shop floor, TU2 welds better (very good vs fair).
C16200Choose it when strength drives the design.
TU2Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C16200 vs TU2: 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.

C16200 vs TU2 — frequently asked
Is C16200 stronger than TU2?
Yes. C16200 has a typical yield strength of 395 MPa (57.3 ksi) against 70 MPa (10.2 ksi) for TU2 — about 5.6 times as much. Tensile strength is 435 MPa (63.1 ksi) vs 230 MPa (33.4 ksi).
Which is cheaper, C16200 or TU2?
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, C16200 or TU2?
C16200, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for TU2; for welding the order is TU2 first (very good, 70/100) then C16200 (fair, 40/100).
