Copper Alloy TP2-H01 vs TP2-O60
Copper Alloy · TP2 temper comparison
TP2-H01 and TP2-O60 are two conditions of the same copper alloy grade, TP2: H01 (quarter hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. TP2-H01 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 70 MPa (10.2 ksi) for TP2-O60, about 193% more; tensile strength follows at 265 MPa (38.4 ksi) vs 225 MPa (32.6 ksi). In exchange, TP2-O60 is the more ductile: elongation 45% versus 25% for TP2-H01, and TP2-H01 is harder (75 HB vs 42 HB). TP2-O60 runs hotter in service (200°C vs 170°C continuous).
TP2-H01Choose it when strength drives the design.
TP2-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
TP2-H01 vs TP2-O60: 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.

TP2-H01 vs TP2-O60 — frequently asked
Is TP2-H01 stronger than TP2-O60?
Yes. TP2-H01 has a typical yield strength of 205 MPa (29.7 ksi) against 70 MPa (10.2 ksi) for TP2-O60 — about 193% more. Tensile strength is 265 MPa (38.4 ksi) vs 225 MPa (32.6 ksi).
Which condition does FabDigit quote by default, H01 or O60?
H58 is the default TP2 condition in the FabDigit quote flow (neither H01 nor O60). 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.
Which is easier to machine, TP2-H01 or TP2-O60?
TP2-H01, by a small margin. Both rate poor for machinability — 25/100 against 18/100 for TP2-O60; for welding the order is TP2-O60 first (excellent, 85/100) then TP2-H01 (very good, 80/100).
