Copper Alloy C86300 vs HBsC1

Copper Alloy · grade comparison

Copper Alloy C86300 and HBsC1 are both copper alloy grades. C86300 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 180 MPa (26.1 ksi) for HBsC1, about 161% more; tensile strength follows at 820 MPa (119 ksi) vs 490 MPa (71.1 ksi). In exchange, HBsC1 is the more ductile: elongation 28% versus 15% for C86300, and C86300 is harder (225 HB vs 100 HB). C86300 is lighter (7.65 g/cm³ vs 8.3 g/cm³ for HBsC1) and HBsC1 conducts heat better (86 W/m·K vs 36 W/m·K). On the shop floor, HBsC1 sits in a lower cost tier (high, $$$$) than C86300 (specialty, $$$$$).

C86300Choose it when strength drives the design, or when weight is the constraint.

HBsC1Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.

C86300 vs HBsC1 — frequently asked

Is C86300 stronger than HBsC1?

Yes. C86300 has a typical yield strength of 470 MPa (68.2 ksi) against 180 MPa (26.1 ksi) for HBsC1 — about 161% more. Tensile strength is 820 MPa (119 ksi) vs 490 MPa (71.1 ksi).

Which is cheaper, C86300 or HBsC1?

HBsC1 is the lower-cost material: it sits in the high tier ($$$$) while C86300 is specialty ($$$$$). 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, C86300 or HBsC1?

HBsC1, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for C86300; for welding the order is HBsC1 first (fair, 35/100) then C86300 (poor, 30/100).
