Palladium definition, a rare metallic element of the platinum group, silver-white, ductile and malleable, harder and fusing more readily than platinum: used chiefly as a catalyst and in dental and other alloys. Symbol: Pd; atomic weight: 106.4; atomic number: 46; specific gravity: 12 at 20Â°C. See more.
Palladium itself has been used as a precious metal in jewelry since 1939, as an alternative to platinum for making white gold. This use resulted from the naturally white color of palladium, which required no rhodium plating. Palladium is much less dense than platinum.alladium is one of the three most popular metals used to make white gold alloys (nickel and silver can also be used). Palladium-gold is a more expensive alloy than nickel-gold, but seldom causes allergic reactions (though certain cross-allergies with nickel may occur).
