Tinned Bare Copper
Stranded soft drawn tinned bare copper conductor is used primarily in applications involving current flow, corrosion resistance, or the need to solder the wire to some component. The addition of a tin coating facilitates the soldering process with only a small price differential over bare copper. A tin coating is also desirable in applications where operating temperatures exceed 100ºC up to 150ºC. At such temperatures the corrosion resistance of bare copper declines and the tin coating acts to protect the surface of the bare copper. The standard minimum thickness of tin coating is 40 micro-inches.
