Copper Alloy C10200 vs C14520
Copper Alloy · grade comparison
Copper Alloy C10200 and C14520 are both copper alloy grades. C14520 is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 69 MPa (10 ksi) for C10200, about 4.4 times as much; tensile strength follows at 335 MPa (48.6 ksi) vs 221 MPa (32.1 ksi). In exchange, C10200 is the more ductile: elongation 45% versus 10% for C14520, and C14520 is harder (100 HB vs 45 HB). C10200 runs hotter in service (250°C vs 200°C continuous) and C10200 conducts heat better (391 W/m·K vs 350 W/m·K). On the shop floor, C14520 machines more easily (excellent vs poor) and C10200 welds better (65 vs 55 out of 100).
C10200Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C14520Choose it when strength drives the design, or when the part is machined in volume.
C10200 vs C14520: 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.

C10200 vs C14520 — frequently asked
Is C14520 stronger than C10200?
Yes. C14520 has a typical yield strength of 305 MPa (44.2 ksi) against 69 MPa (10 ksi) for C10200 — about 4.4 times as much. Tensile strength is 335 MPa (48.6 ksi) vs 221 MPa (32.1 ksi).
Which is cheaper, C10200 or C14520?
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, C10200 or C14520?
C14520. Its machinability rates excellent (88/100) against poor (22/100) for C10200; for welding the order is C10200 first (good, 65/100) then C14520 (good, 55/100).
