Bulk Rolls can all be purchased here at Nimrod Copper. 4 Mil Copper Foil (.004) is high quality copper used extensively for manufacturing and R&D projects.

Copper Specifications

  • 4 Mil (.004 inch) Rolled Copper
  • 110-anneal (Electrolytic Tough Pitch or ETP, dead soft)
  • ASTM-B152
  • Min 99.9% CU

Key Features

  • Approximately 7-8 times as thick as average household aluminum foil (i.e., .0005") or approximately the thickness of a sheet of copier paper (.004").
  • A good choice when 5 mil (.005") seems a little too thick or heavy.
  • Easy to cut with scissors or paper cutter.
  • Does not tear by hand.
  • Dead soft, very pliable.
  • Art work, wall hanging, etc.

4 Mil is excellent for tooling and will dent easily with a light touch but will not hold its shape under pressure. Use it to create designs by emboss drawing, denting, punching, piercing, rub-transferring, tracing, origami, and hammering (Repousse).
