Collected tables for a wide variety of alloys is not trivial to find.
I'm sure there is one in a library somewhere, but in the mean time I
found that "brass" (No exact composition, but I can only assume that
simply brass would refer to 33%zinc or at least give a number that is in
the ballpark) has a latent heat of 168kJ/kg. This number was taken from:
"Engineering Formulas" by Kurt and Reiner Gieck, 7th Edition

I just had it laying around, but it didn't have a very extensive table.
Just in case you didn't know, if you can find either the heat of
vaporization or the heat of sublimination you can calculate the
remaining heat. (Hfusion + Hvaporization = Hsublimination)
