Copper Alloy T2-H08 vs T2-H10
Copper Alloy · T2 temper comparison
T2-H08 and T2-H10 are two conditions of the same copper alloy grade, T2: H08 (spring hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. T2-H10 is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 365 MPa (52.9 ksi) for T2-H08, about 7% more; tensile strength follows at 425 MPa (61.6 ksi) vs 400 MPa (58 ksi). In exchange, T2-H08 is the more ductile: elongation 4% versus 2% for T2-H10, and T2-H10 is harder (125 HV vs 118 HV). T2-H08 runs hotter in service (120°C vs 100°C continuous).
T2-H08Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
T2-H10Choose it when strength drives the design.
T2-H08 vs T2-H10: 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.

T2-H08 vs T2-H10 — frequently asked
Is T2-H10 stronger than T2-H08?
Yes. T2-H10 has a typical yield strength of 390 MPa (56.6 ksi) against 365 MPa (52.9 ksi) for T2-H08 — about 7% more. Tensile strength is 425 MPa (61.6 ksi) vs 400 MPa (58 ksi).
Which condition does FabDigit quote by default, H08 or H10?
M is the default T2 condition in the FabDigit quote flow (neither H08 nor H10). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose T2-H08 over T2-H10?
Pick T2-H08 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick T2-H10 when strength drives the design.
