Copper Alloy C17200 vs C90700
Copper Alloy · grade comparison
Copper Alloy C17200 and C90700 are both copper alloy grades. C17200 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 152 MPa (22 ksi) for C90700, about 71% more; tensile strength follows at 490 MPa (71.1 ksi) vs 305 MPa (44.2 ksi). C17200 is the more ductile: elongation 45% versus 12% for C90700, and C17200 is harder (105 HB vs 80 HB). C17200 is lighter (8.26 g/cm³ vs 8.77 g/cm³ for C90700) and C17200 is stiffer (128 GPa vs 110 GPa). On the shop floor, C90700 machines more easily (45 vs 35 out of 100), C17200 welds better (fair vs poor), and C90700 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.
C90700Choose it when the part sees heat, or when the part is machined in volume.
C17200 vs C90700: 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 C90700 — frequently asked
Is C17200 stronger than C90700?
Yes. C17200 has a typical yield strength of 260 MPa (37.7 ksi) against 152 MPa (22 ksi) for C90700 — about 71% more. Tensile strength is 490 MPa (71.1 ksi) vs 305 MPa (44.2 ksi).
Which is cheaper, C17200 or C90700?
C90700 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 C90700?
C90700, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for C17200; for welding the order is C17200 first (fair, 45/100) then C90700 (poor, 25/100).
