Copper Alloy C17510 vs TBe1.9
Copper Alloy · grade comparison
Copper Alloy C17510 and TBe1.9 are both copper alloy grades. TBe1.9 is the stronger of the two: yield strength 1,030 MPa (149 ksi) against 170 MPa (24.7 ksi) for C17510, about 6.1 times as much; tensile strength follows at 1,200 MPa (174 ksi) vs 310 MPa (45 ksi). In exchange, C17510 is the more ductile: elongation 25% versus 4% for TBe1.9, and TBe1.9 is harder (360 HB vs 70 HB). TBe1.9 is lighter (8.26 g/cm³ vs 8.75 g/cm³ for C17510) and TBe1.9 conducts heat better (118 W/m·K vs 105 W/m·K). On the shop floor, TBe1.9 machines more easily (fair vs poor), C17510 welds better (good vs fair), and TBe1.9 sits in a lower cost tier (high, $$$$) than C17510 (specialty, $$$$$).
C17510Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
TBe1.9Choose it when strength drives the design, or when weight is the constraint.
C17510 vs TBe1.9: 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.
