Palladium Plating

Palladium has often been used as an alternative to gold, providing a functional alternative to connectivity and wire bonding at a much lower cost. Palladium has excellent corrosion resistance and is known for its superb wear-resistance properties. Similar to gold, Palladium does not oxidize or chemically react in corrosive environments.

Palladium is harder than gold so it does wear better and because of its low contact resistance it’s ideal for applications requiring contact surfaces for soldering and wire bonding. It’s also used quite extensively as a barrier coat between nickel or copper alloyed base materials and gold.

The most common use of Palladium is in the manufacture of automotive catalytic converters.

Specifications used for Palladium plating are typically Mil-P-45209 and ASTM B679.
