Linear thermal expansion coefficient conductor material

When an object is heated or cooled, its length change by an amount proportional to the original length and the change in temperature.

The values were taken or derived from, whereby the values typically are given in unit m$^{-6}$/(m.K):

Note: Greek letter $\chi$ is used because $\alpha$ was in use.
