adding copper to kettle

[Beer_Punk]

I recently aquired a 40 qt aluminum tamale pot. I also, then, aquired a piece of copper from work that is big enough to cover the bottom. I've heard that aluminum isn't very effecient for distributing heat. I have seen copper clad pots and pans at the store, that looks like a good happy medium (easy guys, not happy ending) if you can't get a copper kettle. How would I go about adhearing (or sticking, for the short bussers) the copper bottom to my alum. kettle?

Rat Pad.

Why don't you just set the kettle ON the copper?

Fyi aluminum pots distribute heat better than stainless steel ones. That is why you see stainless clad pots with either copper or aluminum. If you look at the stainless pots at b3 I am pretty sure that they are 3 ply stainless aluminum stainless.

ok here is the discription from more beers site
Tri-Clad Bottom
Our Heavy Duty Brew Kettles are built with a tri-clad bottom featuring an aluminum core sandwiched between two layers of stainless steel. Aluminum allows for even heat distribution while the food-grade stainless steel is the only metal in contact with your wort. Even heat distribution eliminates hot spots, which prevents scorching of your malt and makes cleanup a breeze!
