View Full Version : The Precious Metal Palladium

Palladium is a sister to platinum, a “noble metal” (member of the the platinum group of metals) with some rather unique properties that ensure a place for it in industry and as a precious metal investment. This fascinating metal is tied closely with platinum from both history and its properties. Even so, important differences remain in physical properties and in today’s supply and demand economics.

Palladium Bullion
Bullion is the form of palladium traded for investment purposes. From palladium metal, palladium coins (or rounds) and bars are made to form a physical product that is bought or sold on the basis of the palladium content. The catch is that only one government makes bullion bars. Only Canada makes palladium bullion coins, and only a select few have issued commemorative palladium coins (which have become collector’s items).

As a leading private mint and bullion dealer, Northwest Territorial Mint is a market maker in all forms of palladium bullion, including the classic Stillwater Palladium.

"“Oh! how many torments lie in the small circle of a wedding rings and rings. (http://www.rokstok.com/learn_about_tungsten_rings.php?eid=4)”

"Tungsten rings have become very popular in recent years and the metal used to make these rings is called tungsten carbide. Tungsten is the hardest metal on the planet. Using the Mohs scale, tungsten rates a 9 out of the highest possible hardness rating of 10."

Tungesten carbide is not a metal it is WC (http://en.wikipedia.org/wiki/Tungsten_carbide), (W = tungsten, c= carbide). It is a carbide, an inorganic material, often treated as a ceramic. Normally WC is mixed with cobalt to make WC/cobalt, a composite of a metal (cobalt) and the carbide, WC, also known as a cemented carbide. Interesting though. This type of material is typically ground and polished with diamond.
