Copper Alloy C26000 vs C41500
Copper Alloy · grade comparison
Copper Alloy C26000 and C41500 are both copper alloy grades. C41500 is the stronger of the two: yield strength 400 MPa (58 ksi) against 105 MPa (15.2 ksi) for C26000, about 3.8 times as much; tensile strength follows at 455 MPa (66 ksi) vs 325 MPa (47.1 ksi). In exchange, C26000 is the more ductile: elongation 62% versus 12% for C41500, and C41500 is harder (128 HB vs 55 HB). C26000 runs hotter in service (200°C vs 150°C continuous).
C26000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C41500Choose it when strength drives the design.
C26000 vs C41500: 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.

C26000 vs C41500 — frequently asked
Is C41500 stronger than C26000?
Yes. C41500 has a typical yield strength of 400 MPa (58 ksi) against 105 MPa (15.2 ksi) for C26000 — about 3.8 times as much. Tensile strength is 455 MPa (66 ksi) vs 325 MPa (47.1 ksi).
Which is cheaper, C26000 or C41500?
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 welds better, C26000 or C41500?
C41500. Its weldability rates fair (45/100) against fair (40/100) for C26000.
