Copper Alloy C12200 vs C17465
Copper Alloy · grade comparison
Copper Alloy C12200 and C17465 are both copper alloy grades. C17465 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 76 MPa (11 ksi) for C12200, about 7.2 times as much; tensile strength follows at 690 MPa (100 ksi) vs 235 MPa (34.1 ksi). In exchange, C12200 is the more ductile: elongation 45% versus 15% for C17465, and C17465 is harder (195 HB vs 45 HB). C17465 is stiffer (138 GPa vs 117 GPa) and C17465 runs hotter in service (300°C vs 200°C continuous). On the shop floor, C17465 machines more easily (good vs poor) and C12200 welds better (excellent vs poor).
C12200Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C17465Choose it when strength drives the design, or when the part sees heat.
C12200 vs C17465: 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 C17465 — frequently asked
Is C17465 stronger than C12200?
Yes. C17465 has a typical yield strength of 550 MPa (79.8 ksi) against 76 MPa (11 ksi) for C12200 — about 7.2 times as much. Tensile strength is 690 MPa (100 ksi) vs 235 MPa (34.1 ksi).
Which is cheaper, C12200 or C17465?
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 C17465?
C17465. Its machinability rates good (65/100) against poor (20/100) for C12200; for welding the order is C12200 first (excellent, 85/100) then C17465 (poor, 25/100).
