Copper Foil

Copper foil is used for crafting of expensive things. They were added to make it harder to get some things, and the texture was based off the the copper plate, but edited around a bit to make it look like it's slightly crumpled.

It is used in making all 3 tiers of the circuit boards. It isn't used to make the tier 4 circuit board, or the Quantum Manipulator, directly. It is however used in the process of making the quantum manipulator.

Trivia

 * Was added to make it harder to get some things.
 * Crazyguy15052 had the idea on a realtime board thing.
 * A crafting table recipe was added as MCE felt like you shouldn't have to get diamond for the industrial cutter to get copper foil. You can use the titanium saw blade, or diamond one, in the crafting table to get it. However, it will only give you 3 foil instead of 6.
