Bonding Ultrasonic 1 and 3 MHz piezoelectric disc transducer

I am looking for the correct adhesive for bonding a Ultrasonic 1 and 3 Mhz piezoelectric transducer disc to an aluminum case. I have been using different products like Araldite at1, loctite cyanoacylate 410 and other epoxy structural adhesives with poor vibration transference results. The best results have been with metal to metal cyanoacylates like loctite 493 and 496, but its vibration transference degraded when it is working at high power for a while. I have been cleaning the two surfaces with pure alcohol and roughening the surface for better adhesion.
If someone has any recommendation on how to do this please let me know. Thanks for you cooperation.

Andres
