Iridium (Ir)

Iridium, a precious metal, has an appearance similar to platinum in that it is white but with a slightly yellowish tint. Iridium, the most corrosion-resistant metal known, is very hard, brittle, and has a low ductility, making it difficult to machine, form, or work.s. Iridium is the most corrosion resistant metal known. It is completely   unattacked by the common mineral acids at normal and high temperatures,   and by cold and boiling aquaregia. It is the most resistant of the   platinum metals to the halogens. It is slightly attacked by fused sodium   and potassium hydroxides and by fused sodium bicarbonate. Iridium is   resistant to anodic corrosion in aqueous electrolytes, but may be   attacked in aqueous potassium cyanide, hydrochloric acid, and ammonium   carbonate solutions under the action of an alternating current.
