Planned use	Creating an infobox for materials

Motivation

This is part of the project of creating an infobox for materials. Linear thermal expansion coefficient is a base data that is needed, i.e, for mecanical devices operating in a wide range of temperatures. --Thibdx (talk) 14:31, 8 August 2018 (UTC)[reply]
