Osmium is a hard, brittle, bluish-white transition metal and is found as a trace element in alloys, mostly in platinum ores. Being the densest, naturally occurring element, with a density of 22.59 g/cm3, its alloys with platinum, iridium, and other platinum group metals are employed in fountain pen nibs, electrical contacts, and other applications where extreme durability and hardness are needed.

1803 by Smithson Tennant, England.
