Palladium is basically characterised by having a good abrasion resistance and a relatively high hardness. It is the ideal metal for diffusion barrier purposes. Palladium has become more important in jewellery industry as a nickel-free and thus non-allergic coating material in the last decades. Palladium electrolytes from METAKEM combine these advantages.
