Properties of Paliney® 6

Paliney® 6 is an age-hardenable palladium silver-based alloy ideally suited for demanding low current sliding electrical contact applications requiring high-wear resistance. This alloy, with over 50 years of reliable service, combines the mechanical features of Beryllium Copper and the stable contact resistance of high noble metals. Because of its noble metal content, Paliney® 6 offers long wear, tarnish resistance and stable contact resistance. This alloy is used in a wide variety of applications, including such products as throttle position, pedal position, electronic engine control sensors, guidance systems, potentiometers, trimmers, communications and bar code reader. Paliney® 6 meets ASTM Standard Specification B563 for electrical contact alloys.
