Copper Alloy C52100 vs C53800
Copper Alloy · grade comparison
Copper Alloy C52100 and C53800 are both copper alloy grades. C52100 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 450 MPa (65.3 ksi) for C53800, about 30% more; tensile strength follows at 660 MPa (95.7 ksi) vs 540 MPa (78.3 ksi). C52100 is the more ductile: elongation 10% versus 8% for C53800, and C52100 is harder (190 HV vs 175 HV). C53800 conducts heat better (69 W/m·K vs 62 W/m·K). On the shop floor, C53800 machines more easily (very good vs poor), C52100 welds better (fair vs poor), and C53800 sits in a lower cost tier (high, $$$$) than C52100 (specialty, $$$$$).
C52100Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C53800Choose it when the part is machined in volume, or when cost is the deciding factor.
C52100 vs C53800: 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.
