Speed of sound in various materials(ms-1)

The following list gives the speed of sound in a number of different materials. Notice that for some the temperature of the material is also given.

Some of these values vary widely depending on the sources. For example the data given for aluminium varies from 5100 ms-1 [the theoretical value ((E/r)1/2)] to 6240 ms-1 in another practical based source.
