Precious Metal AgCu-Eutectic-AB vs AgCu-Eutectic-H02

Precious Metal · AgCu-Eutectic temper comparison

AgCu-Eutectic-AB and AgCu-Eutectic-H02 are two conditions of the same precious metal grade, AgCu-Eutectic: AB (as built (as printed)) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. AgCu-Eutectic-H02 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 150 MPa (21.8 ksi) for AgCu-Eutectic-AB, about 120% more; tensile strength follows at 420 MPa (60.9 ksi) vs 275 MPa (39.9 ksi). In exchange, AgCu-Eutectic-AB is the more ductile: elongation 18% versus 10% for AgCu-Eutectic-H02, and AgCu-Eutectic-H02 is harder (105 HB vs 60 HB). AgCu-Eutectic-AB runs hotter in service (300°C vs 180°C continuous). On the shop floor, AgCu-Eutectic-H02 machines more easily (good vs fair).

AgCu-Eutectic-ABChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

AgCu-Eutectic-H02Choose it when strength drives the design, or when the part is machined in volume.
