Copper Alloy C50700-H02 vs C50700-H08
Copper Alloy · C50700 temper comparison
C50700-H02 and C50700-H08 are two conditions of the same copper alloy grade, C50700: H02 (half hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C50700-H08 is the stronger of the two: yield strength 505 MPa (73.2 ksi) against 340 MPa (49.3 ksi) for C50700-H02, about 49% more; tensile strength follows at 550 MPa (79.8 ksi) vs 405 MPa (58.7 ksi). In exchange, C50700-H02 is the more ductile: elongation 14% versus 4% for C50700-H08, and C50700-H08 is harder (170 HB vs 120 HB). C50700-H02 runs hotter in service (190°C vs 150°C continuous).
C50700-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C50700-H08Choose it when strength drives the design.
C50700-H02 vs C50700-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.
