  • What Are Platinum Group Metals (PGMs) The Balance

    Dec 10 2018 · The platinum group metals (PGMs) are six transitional metal elements that are chemically physically and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare the six metals naturally occur in the same ore bodies. They are highly durable and due to their high value often recycled giving them long life cycles.
