Copper Alloy C50200 vs C51000
Copper Alloy · grade comparison
Copper Alloy C50200 and C51000 are both copper alloy grades. C50200 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 140 MPa (20.3 ksi) for C51000, about 129% more; tensile strength follows at 370 MPa (53.7 ksi) vs 340 MPa (49.3 ksi). In exchange, C51000 is the more ductile: elongation 60% versus 12% for C50200, and C50200 is harder (112 HB vs 80 HB). C51000 runs hotter in service (200°C vs 150°C continuous) and C50200 conducts heat better (215 W/m·K vs 69 W/m·K). On the shop floor, C50200 welds better (good vs fair) and C50200 sits in a lower cost tier (high, $$$$) than C51000 (specialty, $$$$$).
C50200Choose it when strength drives the design, or when it will be welded.
C51000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C50200 vs C51000: 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.

C50200 vs C51000 — frequently asked
Is C50200 stronger than C51000?
Yes. C50200 has a typical yield strength of 320 MPa (46.4 ksi) against 140 MPa (20.3 ksi) for C51000 — about 129% more. Tensile strength is 370 MPa (53.7 ksi) vs 340 MPa (49.3 ksi).
Which is cheaper, C50200 or C51000?
C50200 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, C50200 or C51000?
C50200, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C51000; for welding the order is C50200 first (good, 55/100) then C51000 (fair, 45/100).
