Osmium Information

Hard blue-white metallic transition element. Found with platinum and used in some alloys with platinum and iridium.

Used to tip gold pen points, instrument pivots, to make electric light filaments. Used for high temp. alloys and pressure bearings. Very hard and resists corrosion better than any other.
