Copper Alloy C14500 vs T2
Copper Alloy · grade comparison
Copper Alloy C14500 and T2 are both copper alloy grades. C14500 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 69 MPa (10 ksi) for T2, about 4.0 times as much; tensile strength follows at 310 MPa (45 ksi) vs 220 MPa (31.9 ksi). In exchange, T2 is the more ductile: elongation 45% versus 18% for C14500, and C14500 is harder (85 HB vs 40 HB). T2 conducts heat better (391 W/m·K vs 350 W/m·K). On the shop floor, C14500 machines more easily (excellent vs poor) and T2 welds better (fair vs poor).
C14500Choose it when strength drives the design, or when the part is machined in volume.
T2Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C14500 vs T2: 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.

C14500 vs T2 — frequently asked
Is C14500 stronger than T2?
Yes. C14500 has a typical yield strength of 275 MPa (39.9 ksi) against 69 MPa (10 ksi) for T2 — about 4.0 times as much. Tensile strength is 310 MPa (45 ksi) vs 220 MPa (31.9 ksi).
Which is cheaper, C14500 or T2?
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, C14500 or T2?
C14500. Its machinability rates excellent (85/100) against poor (20/100) for T2; for welding the order is T2 first (fair, 40/100) then C14500 (poor, 25/100).
