KMG Gold Recycling® Gold Buyers Rhodium FAQ

Rhodium is a chemical element with the atomic symbol Rh

Rhodium is a rare, silvery-white, hard and chemically inert transition metal and a member of the platinum group metals. Because of its rarity, rhodium is usually alloyed with platinum or palladium and applied in high-temperature and corrosion-resistive coatings.

The primary use of this element is in automobiles as a catalytic converter, which converts harmful emissions from the engine into less harmful gases.

Rhodium is used in jewelry and for decorations. It is electroplated on white gold and platinum to give it a reflective white surface. This is known as rhodium flashing in the jewelry business. It also may be used in coating sterling silver in order to strengthen the metal from tarnishing.

Solid (pure) rhodium jewelry is very rare, because the metal has both high melting point and poor malleability (making such jewelry very hard to fabricate) rather than due to its high price.

Rhodium has also been used for honours, or to symbolize wealth, when more commonly used metals such as silver, gold or platinum are deemed insufficient. In 1979 the Guinness Book of World Records gave Paul McCartney a rhodium-plated disc for being history's all-time best-selling songwriter and recording artist.

Rhodium is a unique element, it is not white gold.
  1. Principal sources of Rhodium are located in South Africa, in river sands of the Ural Mountains, and in North America, including the copper-nickel sulfide mining area of the Sudbury, Ontario region.
  2. Rhodium is used as an allaying agent for hardening and improving the corrosion resistance of platinum and palladium. These alloys are used in furnace windings, bushings for glass fiber production, electrodes for aircraft spark plugs, and laboratory crucibles.
  3. Rhodium is one of the rarest and, with the price of about $80,000/kg in 2010, is the most expensive precious metal.
  4. Rhodium is not magnetic. However often times nickel is underneath rhodium plating on jewelry causing a magnetic attraction.
