Are there publicly available datasets of physical and chemical properties for (industrially produced) metals and alloys?
MatWeb.com's page Metal & Alloy Composition Search has a searchable database, where you can search for metals and alloys by either (or both) of:
Choose a Material Category
Choose up to 3 Material Compositions
or search the entire UNS (Unified Numbering System for Metals and Alloys), which
is a systematic scheme in which each metal is designated by a letter followed by five numbers. It is a composition-based system of commercial materials and does not guarantee any performance specifications or exact composition with impurity limits. Other nomenclature systems have been incorporated into the UNS numbering system to minimize confusion.
The data sheets provide details about the physical, chemical, mechanical, electrical, thermal and optical properties, and the properties of the components of alloys are provided. Further references are provided in each fact sheet.
