Platinum

A heavy, malleable, ductile, precious, gray-white transition metal, platinum is resistant to corrosion and occurs in some nickel and copper ores along with some native deposits. The most common use of platinum is as a catalyst in chemical reactions. Platinum is used as an alloying agent for various metal products, including fine wires, noncorrosive laboratory containers, medical instruments, jewelry, dental equipment, electrical contacts, and thermocouples. Platinum's wear and tarnish resistance characteristics are well suited for making fine jewelry. Platinum is more precious than gold.
