The Unified Numbering System was developed by ASTM and SAE in order to correlate a number of varied numbering systems for commercial alloys and metals. The UNS number is an identification number for each alloy and metal.
The following table is a list of rare earth and earth-like metals and alloys with their UNS numbering system ranging from E00001–E99999.
