Material Properties Database

TPSX is a material database for analysts, engineers and designers in the aerospace field offering data on over 1500 materials, compiled by various NASA Centers and industry sources. Most of the materials are designed for aerospace applications and much of the data is temperature dependent. Property data can be exported in a format compatible many popular thermal analysis software packages including SINDA/FLUINT and Thermal Desktop.

You must be a registered user to access TPSX. If you are not yet registered, please visit the TPSX Registration Page at tpsx.arc.nasa.gov/registration/reg.html. If you are already registered, you can log in at tpsx.arc.nasa.gov/.

Sample Usage

Below is an example of the TPSX Material Property Database export to SINDA/FLUINT and Thermal Desktop for 302 stainless steel.
