Copper Alloy C17200 vs Cu-OF
Copper Alloy · grade comparison
Copper Alloy C17200 and Cu-OF are both copper alloy grades. C17200 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 150 MPa (21.8 ksi) for Cu-OF, about 73% more; tensile strength follows at 490 MPa (71.1 ksi) vs 230 MPa (33.4 ksi). C17200 is the more ductile: elongation 45% versus 30% for Cu-OF, and C17200 is harder (105 HB vs 65 HB). C17200 is lighter (8.26 g/cm³ vs 8.94 g/cm³ for Cu-OF) and C17200 is stiffer (128 GPa vs 115 GPa). On the shop floor, C17200 machines more easily (fair vs poor), Cu-OF welds better (good vs fair), and Cu-OF sits in a lower cost tier (high, $$$$) than C17200 (specialty, $$$$$).
C17200Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Cu-OFChoose it when the part sees heat, or when it will be welded.
C17200 vs Cu-OF: 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.

C17200 vs Cu-OF — frequently asked
Is C17200 stronger than Cu-OF?
Yes. C17200 has a typical yield strength of 260 MPa (37.7 ksi) against 150 MPa (21.8 ksi) for Cu-OF — about 73% more. Tensile strength is 490 MPa (71.1 ksi) vs 230 MPa (33.4 ksi).
Which is cheaper, C17200 or Cu-OF?
Cu-OF is the lower-cost material: it sits in the high tier ($$$$) while C17200 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, C17200 or Cu-OF?
C17200. Its machinability rates fair (35/100) against poor (20/100) for Cu-OF; for welding the order is Cu-OF first (good, 55/100) then C17200 (fair, 45/100).
