Iridium is nearly as dense as the densest metal osmium and is the most corrosion-resistant metal element, resistant to air, water, salts and acids. Because of its hardness, iridium is difficult to fabricate into usable parts, but the same characteristics that make it difficult to work with also make it a valuable additive for strengthening alloys.
