Iridium is the second most dense element and considered the most corrosion-resistant element because of its ability to resist attack from gases, salts and acids. Due to its rarity, global iridium production totals only about 3 tonnes per year. The is most often extracted as a by-product of nickel and platinum group metal-rich ores.
