Copper Alloy C26200-H02 vs C26200-H08
Copper Alloy · C26200 temper comparison
C26200-H02 and C26200-H08 are two conditions of the same copper alloy grade, C26200: H02 (half hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C26200-H08 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 379 MPa (55 ksi) for C26200-H02, about 24% more; tensile strength follows at 690 MPa (100 ksi) vs 490 MPa (71.1 ksi). In exchange, C26200-H02 is the more ductile: elongation 23% versus 4% for C26200-H08, and C26200-H08 is harder (185 HB vs 125 HB). C26200-H02 runs hotter in service (200°C vs 150°C continuous).
C26200-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C26200-H08Choose it when strength drives the design.
C26200-H02 vs C26200-H08: 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.
