The invention is a laminate made of very thin copper sheet preferably between 0.0005 and 0.01 inches thick, aluminum sheet preferably between 0.004 and 0.04 inches thick, and adhesive between the copper and aluminum sheets. The cost of the aluminum, adhesive, and the manufacturing process combined are much less expensive than solid copper sheet of 0.020 inches in thickness. However, when the copper sheet of the laminate is on the outside, the aesthetic qualities are indistinguishable from heavyweight solid copper sheet.
