My experience is a 20cm wide 4 m long copper strip glued to a concrete base outdoor in the Netherlands: from +32°C to -20°C. Up till now no problems.

I am consulting on a local sun sculpture which requires that an aluminum
backing be glued to 6" x 24" stainless steel mirrors.  They can't be screwed
on for fear that the screws and holes might distort the mirror, and hence the
image.  The temperature exposure will range from -20 to 120 degrees
Fahrenheit seasonally, and I think that the glue must be able to forgive the
small difference in the metals' coefficients of expansion.

Any recommendations?  Silicon glue, polyurethane, epoxy, or something else?
Thanks-
