Aluminium Surface Wave Velocity

Hi,
Does anybody have a reference that quotes a range of Surface Wave Velocities for different Aluminium Alloys?

I need an approximate figure to be able to calculate the second Critical Angle to generate surface waves in Aluminium Castings, or alternatively, an Incident Angle in Water to gererate these.

Dear Godfrey,
I have a couple of references that I found a few years ago that you can probably use as a guide.

Al 1100-0 (2SO) Velocity of sound (Surface) 2900m/s

Al 2024 T4 (24ST)Velocity of sound (Surface) 2950m/s

These came from the Xactex Corp booklet dated August 1995

Regards

Neil Burleigh
