Metals By Type
By Terence Bell
Find information on every metal, based on its industrial classification.
The term 'base metals' commonly refers to industrial, non-ferrous metals.

The term 'minor metals' is used to describe about 40 elemental metals that are normally produced as by-products and not traded on any major exchanges.
- Rare Earth Elements (REEs)
Ferrous metals are distinguished by their iron content and are used primarily in the production of steel.
Platinum Group Metals (PGMs)
The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically and anatomically similar.
Rare Earth Metals
The rare earth or lanthanide metals include elements with the atomic numbers 57 through 71. Due to their similar properties and tendency to be found with the lanthanides, scandium (atomic number 21) and yttrium (39) are also normally referred to as rare earth elements.
Common alloys that are used in industry for their specific mechanical, physical and chemical properties.
