Copper Alloy C83400 vs HBsC1
Copper Alloy · grade comparison
Copper Alloy C83400 and HBsC1 are both copper alloy grades. HBsC1 is the stronger of the two: yield strength 180 MPa (26.1 ksi) against 69 MPa (10 ksi) for C83400, about 161% more; tensile strength follows at 490 MPa (71.1 ksi) vs 234 MPa (33.9 ksi). In exchange, C83400 is the more ductile: elongation 35% versus 28% for HBsC1, and HBsC1 is harder (100 HB vs 50 HB). HBsC1 is lighter (8.3 g/cm³ vs 8.8 g/cm³ for C83400) and HBsC1 is stiffer (103 GPa vs 96.5 GPa). On the shop floor, C83400 machines more easily (good vs poor) and C83400 welds better (45 vs 35 out of 100).
C83400Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
HBsC1Choose it when strength drives the design, or when weight is the constraint.
C83400 vs HBsC1: 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.

C83400 vs HBsC1 — frequently asked
Is HBsC1 stronger than C83400?
Yes. HBsC1 has a typical yield strength of 180 MPa (26.1 ksi) against 69 MPa (10 ksi) for C83400 — about 161% more. Tensile strength is 490 MPa (71.1 ksi) vs 234 MPa (33.9 ksi).
Which is cheaper, C83400 or HBsC1?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C83400 or HBsC1?
C83400. Its machinability rates good (58/100) against poor (32/100) for HBsC1; for welding the order is C83400 first (fair, 45/100) then HBsC1 (fair, 35/100).
