Iridium

A precious metal that is extremely resistant to corrosion. It is used mainly for scientific and industrial purposes for which resistance to corrosion at high temperatures is needed. With only three metric tons of iridium produced and used each year, it is traded as a commodity on various security exchanges. Like many precious metals, iridium is volatile, but generally maintains relatively high prices.
