Iridium
One of the platinum group of metals. Iridium occurs in the metallic state, alloyed with crude platinum to the extent of about 4%. It is a greyish-white, lustrous metal, which, in common with rhodium, is not appreciably attacked by any acid or mixture of acids. It is absolutely unoxidisable in air, even at red heat, and thus the most stable and resistant of metals. Iridium has hardening effect on platinum, and platinum-iridium alloys are frequently in use, such alloys containing between 5% and 20% of iridium.
