For the A330 in clean configuration alphamax (normal law) is greater than alpha_SW (alternate law) at all Mach numbers less than 0.86. I do not know the value of alphaCLmax, except that it is greater than alphamax as explained in numerous Airbus documents. At high Mach number alphamax is actually buffet onset, as explained in the FCOM.
P.S.
I forgot to mention that we know one point of the alphaCLmax vs Mach curve: AF447 stalled at 10° AoA / M.67.
