Listing of Material Library.

This is a listing of all the elements in all the materials that are included in the ARMI material library. Many of the materials in this library are academic in quality and contents. Some have temperature dependent properties, but some don’t. You can provide your own proprietary material properties via a plugin.

More info about the materials here: armi.materials.
