Copper Alloy C33000 vs C36200
Copper Alloy · grade comparison
Copper Alloy C33000 and C36200 are both copper alloy grades. C36200 is the stronger of the two: yield strength 310 MPa (45 ksi) against 110 MPa (16 ksi) for C33000, about 182% more; tensile strength follows at 400 MPa (58 ksi) vs 340 MPa (49.3 ksi). In exchange, C33000 is the more ductile: elongation 55% versus 25% for C36200, and C36200 is harder (115 HB vs 55 HB). C33000 is stiffer (103 GPa vs 97 GPa). On the shop floor, C36200 machines more easily (excellent vs very good), C33000 welds better (25 vs 15 out of 100), and C36200 sits in a lower cost tier (premium, $$$) than C33000 (high, $$$$).
C33000Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
C36200Choose it when strength drives the design, or when the part is machined in volume.
C33000 vs C36200: 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.
