  • Copper Sheet Thickness Guide BasicCopper

    8 MIL (.008 inches thick) 32 gauge: The 8 mil copper is approximately 11 12 times thicker than typical household aluminum foil and 1.5 times thicker than the 5 mil. This is a heavy-duty tooling foil. 8 mil can be cut fairly easily with scissors and is still very pliable. It may hold shape a little better than the 5 MIL, but will not bear much weight and will yield to increasing pressure.
