Copper Alloy C51000 vs C62200
Copper Alloy · grade comparison
Copper Alloy C51000 and C62200 are both copper alloy grades. C62200 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 140 MPa (20.3 ksi) for C51000, about 136% more; tensile strength follows at 655 MPa (95 ksi) vs 340 MPa (49.3 ksi). In exchange, C51000 is the more ductile: elongation 60% versus 20% for C62200, and C62200 is harder (170 HB vs 80 HB). C62200 is lighter (7.53 g/cm³ vs 8.86 g/cm³ for C51000) and C62200 is stiffer (117 GPa vs 110 GPa). On the shop floor, C62200 welds better (good vs fair) and C62200 sits in a lower cost tier (high, $$$$) than C51000 (specialty, $$$$$).
C51000Choose it when the part is bent, formed or impact-loaded.
C62200Choose it when strength drives the design, or when weight is the constraint.
C51000 vs C62200: 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.

C51000 vs C62200 — frequently asked
Is C62200 stronger than C51000?
Yes. C62200 has a typical yield strength of 330 MPa (47.9 ksi) against 140 MPa (20.3 ksi) for C51000 — about 136% more. Tensile strength is 655 MPa (95 ksi) vs 340 MPa (49.3 ksi).
Which is cheaper, C51000 or C62200?
C62200 is the lower-cost material: it sits in the high tier ($$$$) while C51000 is specialty ($$$$$). 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, C51000 or C62200?
C62200, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C51000; for welding the order is C62200 first (good, 65/100) then C51000 (fair, 45/100).
