Copper Foil Sheets 5 Mil (.005 inches) 36 gauge thick copper alloy 110 (99.9% CU) smooth commercial finish/annealed (dead soft and very malleable) and manufactured to ASTM-B152 specifications. These are high quality premium copper sheets for embossing, repousse, various home improvement projects, do it yourself projects, construction projects, and arts and crafts projects as well as manufacturing, electrical applications including rf shielding, research/development, and much more. Some customers also use this thickness for tabletops, bar tops, and counter tops-however when using 5 mil for these applications, we do strongly recommend attaching the copper to a substrate and applying an epoxy for long term durability! Available in widths of 3", 6", 12", 18", and 24" and 36." 5 mil copper foil does not tear by hand, but can be easily cut with scissors. It is extremely pliable.
