Copper Ingot

Copper Ingots can be obtained by smelting Copper Ore or Copper Dust in an Iron Furnace. This metal is used for production of basic Cables and Bronze, as well as several other machines.

Note that there's two copper ingots in Tekkit: Copper from IC2 and copper from Redpower2. These are interchangable and should work, i.e. make IC2 stuff with Redpower copper.
