About Platinum-Group ElementsHide

A group of six metallic elements: Iridium, Osmium, Palladium, Platinum, Rhodium, and Ruthenium and their various natural alloys.

The platinum-group elements often occur in native form, often together and are often alloyed with each other and iron or other metals. They are frequently referred to in the literature as the PGE's.
