Os=OSMIUM
Osmium is a hard, shiny transition metal. Under most conditions, it is the element with the highest density (about twice as heavy as lead).
Description: Osmium is a non-corroding high-melting-point hard metal and is the densest element.
Where It's Used: Osmium is mainly used to make hard metal alloys. You can find it in ball point pen tips, record needles, electrical contacts, and other metal components where friction needs to be mitigated.
