Copper Alloy C82200 vs Cu-ETP1
Copper Alloy · grade comparison
Copper Alloy C82200 and Cu-ETP1 are both copper alloy grades. C82200 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 70 MPa (10.2 ksi) for Cu-ETP1, about 5.9 times as much; tensile strength follows at 620 MPa (89.9 ksi) vs 220 MPa (31.9 ksi). In exchange, Cu-ETP1 is the more ductile: elongation 40% versus 5% for C82200, and C82200 is harder (195 HB vs 45 HB). C82200 is stiffer (130 GPa vs 117 GPa) and C82200 runs hotter in service (300°C vs 200°C continuous).
C82200Choose it when strength drives the design, or when the part sees heat.
Cu-ETP1Choose it when the part is bent, formed or impact-loaded.
C82200 vs Cu-ETP1: 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.

C82200 vs Cu-ETP1 — frequently asked
Is C82200 stronger than Cu-ETP1?
Yes. C82200 has a typical yield strength of 415 MPa (60.2 ksi) against 70 MPa (10.2 ksi) for Cu-ETP1 — about 5.9 times as much. Tensile strength is 620 MPa (89.9 ksi) vs 220 MPa (31.9 ksi).
Which is cheaper, C82200 or Cu-ETP1?
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.
When should I choose C82200 over Cu-ETP1?
Pick C82200 when strength drives the design, or when the part sees heat. Pick Cu-ETP1 when the part is bent, formed or impact-loaded.
