Suzanne,

I am not a metallurgist, but I believe that hardening/annealing and minor
alloying constituents have little effect on Youngs modulus and Poissons
ratio - I have always used values of 130GPa and 0.44 for anything described
as "copper"

p.s. did you get my response regarding class room demos? I got an
incomprehensible error message in response to it - something to do
with your mail domain, but I know other list members did receive it.
