Table of Sound Velocities

Velocities will vary according to the precise grade and processing conditions of the
material being measured.
This table is included as a guide only.
Wherever possible, the Gauge should always be calibrated on the material
under test.
These Velocities are given in good faith and are believed to be accurate
within the limits described above.
No liability is accepted for errors.
Velocities given are the compressional wave velocity c
