NIST Alloy Data


TRC alloy data site

About and Purpose

The NIST Alloy data web application ( provides access to thermophysical property data with a focus on unary, binary, and ternary metal systems. The data collection effort has been conducted in an effort with the Materials Genome Initiative in an effort to increase materials discovery. The data collection effort started in 2014 with a trial system of aluminum, magnesium, and silicon (and their binaries and ternary system data).  Progress has been made collecting data for pure elemental data using a modified version of the Guided Data Capture program used in our Journal Collaboration effort.  The site went up Jan. 1 2017, and will continue to grow.    


  • No cost access to thermophysical property data of metal-based systems
  • Detailed descriptions of key elements of each dataset including:
    •  Processing, uncertainties, and purity information from experimental investigation.
    • Full citation information for each datum. 
  • Various search options based on selected metallic elements 





There is no cost  to access the NIST Alloys Data web application.
