Palladium Plating Solutions

Palladium refining commonly uses the aqua regia process to dissolve the metal, sulfide precipitation to separate it, and electrolytic refining to deposit it onto electrodes. Other methods include chemical precipitation and solvent extraction for further purification.

In some applications, palladium cobalt plating is used, where a small percentage of cobalt is added to the palladium plating solution to improve the hardness and resistance of the coating.

The price of palladium is high due to its limited supply and strong demand for use in catalytic converters. Additionally, its high refining costs and investment interest contribute to its elevated price.

Gold plating is renowned for its excellent conductivity, resistance to oxidation, and aesthetic appeal, making it a preferred choice in luxury items like jewelry and high-end electronics. However, gold is more expensive, which can increase costs, especially in large-scale applications.

On the other hand, palladium plating offers a more cost-effective solution while still providing excellent corrosion resistance and good electrical conductivity. Palladium plating is also harder and more wear-resistant than gold, making it suitable for industrial applications where durability is crucial.
