Copper Alloy C17300 vs TBe1.9
Copper Alloy · grade comparison
Copper Alloy C17300 and TBe1.9 are both copper alloy grades. TBe1.9 is the stronger of the two: yield strength 1,030 MPa (149 ksi) against 220 MPa (31.9 ksi) for C17300, about 4.7 times as much; tensile strength follows at 1,200 MPa (174 ksi) vs 470 MPa (68.2 ksi). In exchange, C17300 is the more ductile: elongation 40% versus 4% for TBe1.9, and TBe1.9 is harder (360 HB vs 110 HB). TBe1.9 runs hotter in service (200°C vs 150°C continuous) and TBe1.9 conducts heat better (118 W/m·K vs 105 W/m·K). On the shop floor, TBe1.9 welds better (fair vs poor) and TBe1.9 sits in a lower cost tier (high, $$$$) than C17300 (specialty, $$$$$).
C17300Choose it when the part is bent, formed or impact-loaded.
TBe1.9Choose it when strength drives the design, or when the part sees heat.
C17300 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.

C17300 vs TBe1.9 — frequently asked
Is TBe1.9 stronger than C17300?
Yes. TBe1.9 has a typical yield strength of 1,030 MPa (149 ksi) against 220 MPa (31.9 ksi) for C17300 — about 4.7 times as much. Tensile strength is 1,200 MPa (174 ksi) vs 470 MPa (68.2 ksi).
Which is cheaper, C17300 or TBe1.9?
TBe1.9 is the lower-cost material: it sits in the high tier ($$$$) while C17300 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, C17300 or TBe1.9?
C17300, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for TBe1.9; for welding the order is TBe1.9 first (fair, 40/100) then C17300 (poor, 15/100).
