Precious Metal AgCu10-H04 vs AgCu10-M
Precious Metal · AgCu10 temper comparison
AgCu10-H04 and AgCu10-M are two conditions of the same precious metal grade, AgCu10: H04 (full hard) versus M (thermomechanically controlled processed). The chemistry is identical, so every difference below comes from the condition. AgCu10-H04 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 105 MPa (15.2 ksi) for AgCu10-M, about 4.0 times as much; tensile strength follows at 480 MPa (69.6 ksi) vs 245 MPa (35.5 ksi). In exchange, AgCu10-M is the more ductile: elongation 20% versus 4% for AgCu10-H04, and AgCu10-H04 is harder (115 HB vs 62 HB). AgCu10-M runs hotter in service (250°C vs 180°C continuous). On the shop floor, AgCu10-H04 machines more easily (very good vs good).
AgCu10-H04Choose it when strength drives the design, or when the part is machined in volume.
AgCu10-MChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AgCu10-H04 vs AgCu10-M: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all precious metal 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.

AgCu10-H04 vs AgCu10-M — frequently asked
Is AgCu10-H04 stronger than AgCu10-M?
Yes. AgCu10-H04 has a typical yield strength of 420 MPa (60.9 ksi) against 105 MPa (15.2 ksi) for AgCu10-M — about 4.0 times as much. Tensile strength is 480 MPa (69.6 ksi) vs 245 MPa (35.5 ksi).
Which condition does FabDigit quote by default, H04 or M?
Annealed is the default AgCu10 condition in the FabDigit quote flow (neither H04 nor M). 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, AgCu10-H04 or AgCu10-M?
AgCu10-H04. Its machinability rates very good (70/100) against good (60/100) for AgCu10-M; for welding the order is AgCu10-M first (good, 65/100) then AgCu10-H04 (good, 60/100).
