PdAg50 Alloy – Deformed Condition: Properties & Applications

The palladium-silver alloy PdAg50, also Pd50Ag50 or 50Pd50Ag, is used as contact material in relays and switches of the telecommunications as well as of the measuring and control technology with voltages in the range 20 to 60 V and switching capacities up to approx. Furthermore, the material is used as Potentiometerlegierung. The material is ductile, corrosion-resistant, less resistant to Pd (pure) Brown Powder effect, abrasion resistant. It is non-cutting and machinable machinable, roll-clad, from the gas phase conditionally separable.
