Copper Alloy C28000 vs C36200
Copper Alloy · grade comparison
Copper Alloy C28000 and C36200 are both copper alloy grades. C36200 is the stronger of the two: yield strength 310 MPa (45 ksi) against 145 MPa (21 ksi) for C28000, about 114% more; tensile strength follows at 400 MPa (58 ksi) vs 372 MPa (54 ksi). In exchange, C28000 is the more ductile: elongation 45% versus 25% for C36200, and C36200 is harder (115 HB vs 75 HB). C28000 is stiffer (105 GPa vs 97 GPa). On the shop floor, C36200 machines more easily (excellent vs good) and C28000 welds better (fair vs poor).
C28000Choose 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.
C28000 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.

C28000 vs C36200 — frequently asked
Is C36200 stronger than C28000?
Yes. C36200 has a typical yield strength of 310 MPa (45 ksi) against 145 MPa (21 ksi) for C28000 — about 114% more. Tensile strength is 400 MPa (58 ksi) vs 372 MPa (54 ksi).
Which is cheaper, C28000 or C36200?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C28000 or C36200?
C36200. Its machinability rates excellent (100/100) against good (55/100) for C28000; for welding the order is C28000 first (fair, 50/100) then C36200 (poor, 15/100).
