Copper Alloy CuAg0.04-H01 vs CuAg0.04-H06

Copper Alloy · CuAg0.04 temper comparison

CuAg0.04-H01 and CuAg0.04-H06 are two conditions of the same copper alloy grade, CuAg0.04: H01 (quarter hard) versus H06 (extra hard). The chemistry is identical, so every difference below comes from the condition. CuAg0.04-H06 is the stronger of the two: yield strength 345 MPa (50 ksi) against 200 MPa (29 ksi) for CuAg0.04-H01, about 73% more; tensile strength follows at 385 MPa (55.8 ksi) vs 260 MPa (37.7 ksi). In exchange, CuAg0.04-H01 is the more ductile: elongation 25% versus 5% for CuAg0.04-H06, and CuAg0.04-H06 is harder (112 HB vs 75 HB). CuAg0.04-H01 runs hotter in service (220°C vs 200°C continuous).

CuAg0.04-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

CuAg0.04-H06Choose it when strength drives the design.

CuAg0.04-H01 vs CuAg0.04-H06 — frequently asked

Is CuAg0.04-H06 stronger than CuAg0.04-H01?

Yes. CuAg0.04-H06 has a typical yield strength of 345 MPa (50 ksi) against 200 MPa (29 ksi) for CuAg0.04-H01 — about 73% more. Tensile strength is 385 MPa (55.8 ksi) vs 260 MPa (37.7 ksi).

Which condition does FabDigit quote by default, H01 or H06?

H04 is the default CuAg0.04 condition in the FabDigit quote flow (neither H01 nor H06). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, CuAg0.04-H01 or CuAg0.04-H06?

CuAg0.04-H06, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for CuAg0.04-H01; for welding the order is CuAg0.04-H01 first (fair, 35/100) then CuAg0.04-H06 (poor, 30/100).
