osmium
Also known as Os, element 76, 76Os
Osmium () is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group. Osmium has the highest density of any stable element and one of the lowest abundances in the Earth's crust. Manufacturers use alloys of osmium with platinum, iridium, and other platinum-group metals for fountain pen nib tipping, electrical contacts, and other applications that require extreme durability and hardness.
AI overview
Osmium is a rare, extremely hard metal that is the densest stable element known to science. Because of its exceptional durability and hardness, manufacturers use osmium alloys in specialized applications like fountain pen nibs and electrical contacts that need to withstand extreme wear.
