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
