Aluminum foil laminated to paperboard panels – unprimed
These are low cost metallic substrates to replace expensive solid metal panels when the primary interest is in appearance. Each card has a 1/4 inch (6.4 mm) diameter hole punched in one end. In addition to lower cost, a major advantage over regular metal panels is that they are much lighter in weight and therefore more conveniently stored.
AGX-2N is unprimed. There is foil on both sides to minimize bake distortion. The bright side is conductive.
