Platinum is the least reactive metal and is resistant to corrosion, even at high temperatures, making it an ideal metal for a number of industrial products. The same Platinum found in Platinum bullion is used in catalytic converters in cars, laboratory equipment, electrical contacts, dentistry equipment and jewelry. In addition to industrial uses, Platinum is, of course, a Precious Metals commodity, available as Platinum coins, Platinum bars and Platinum rounds. Due to its rarity, Platinum, is historically more expensive than Gold during times of economic stability and growth. During times of economic uncertainty, the Platinum price can often decrease because of reduced industrial demand.
