Copper Alloy C33000 vs C33200
Copper Alloy · grade comparison
Copper Alloy C33000 and C33200 are both copper alloy grades. C33200 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 110 MPa (16 ksi) for C33000, about 3.8 times as much; tensile strength follows at 515 MPa (74.7 ksi) vs 340 MPa (49.3 ksi). In exchange, C33000 is the more ductile: elongation 55% versus 7% for C33200, and C33200 is harder (140 HB vs 55 HB). C33000 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C33200 machines more easily (82 vs 70 out of 100).
C33000Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C33200Choose it when strength drives the design, or when the part is machined in volume.
C33000 vs C33200: 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.

C33000 vs C33200 — frequently asked
Is C33200 stronger than C33000?
Yes. C33200 has a typical yield strength of 415 MPa (60.2 ksi) against 110 MPa (16 ksi) for C33000 — about 3.8 times as much. Tensile strength is 515 MPa (74.7 ksi) vs 340 MPa (49.3 ksi).
Which is cheaper, C33000 or C33200?
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, C33000 or C33200?
C33200, by a small margin. Both rate very good for machinability — 82/100 against 70/100 for C33000; for welding the order is C33000 first (poor, 25/100) then C33200 (poor, 20/100).
