HTH!

If that would perchance be a composition Cu:77.5% Zn:20.5% Al:2% As:trace alloy (C68700), the machinery's handbook says:

tensile strength 60ksi, yield strength 27ksi, elongation 55%, machinability rating 30 (with 100 for free-cutting brass)

good for cold working: forming/ bending

good corrosion resistance (use in heat exchanger tubing/ plates-condensers, evaporators)

hope this helps

Sorry, didn't notice your 'thermal properties' bit...

But that's easy. Cu being much more conductive than Al, your best bet is to max out the Cu content. (keeping in mind that Cu-Al alloys are solid solution alloys, therefore more or less displaying an averaged(?) mix of physical properties)

Still, not being a metallurgist myself, you may want to take my advice with a piece of salt.

I would not try Cu-Al-Zn,

but try CuAl - often used for seawater resitant parts,

or CuAg - too high cost for most applications.

There should be a book: Copper and copper alloys!
