Copper Alloy C10100 vs Cu-DHP

Copper Alloy · grade comparison

Copper Alloy C10100 and Cu-DHP are both copper alloy grades. Cu-DHP is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 69 MPa (10 ksi) for C10100, about 3.2 times as much; tensile strength follows at 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi). In exchange, C10100 is the more ductile: elongation 45% versus 20% for Cu-DHP, and Cu-DHP is harder (70 HB vs 45 HB). C10100 runs hotter in service (200°C vs 150°C continuous) and C10100 conducts heat better (391 W/m·K vs 339 W/m·K). On the shop floor, Cu-DHP sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).

C10100Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Cu-DHPChoose it when strength drives the design, or when cost is the deciding factor.

C10100 vs Cu-DHP — frequently asked

Is Cu-DHP stronger than C10100?

Yes. Cu-DHP has a typical yield strength of 220 MPa (31.9 ksi) against 69 MPa (10 ksi) for C10100 — about 3.2 times as much. Tensile strength is 275 MPa (39.9 ksi) vs 235 MPa (34.1 ksi).

Which is cheaper, C10100 or Cu-DHP?

Cu-DHP is the lower-cost material: it sits in the high tier ($$$$) while C10100 is specialty ($$$$$). 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, C10100 or Cu-DHP?

Cu-DHP, by a small margin. Both rate poor for machinability — 25/100 against 18/100 for C10100.
