Bare vs Tinned Copper Wire
Electrical-grade copper wire is typically specified by conductivity grade and whether a tinned finish is needed for the application's environment.
Bare Electrical Copper Wire
Uncoated copper wire for standard electrical and winding applications where no special corrosion protection is needed.
Tinned Copper Wire
Wire with a thin tin coating for improved solderability and corrosion resistance in marine or humid-environment electrical work.
Construction Types Available
Solid Wire
Single-strand wire for general wiring and winding.
Stranded Wire
Multiple fine strands twisted together for greater flexibility, used where the wire will be flexed repeatedly.
Where Copper Wire Is Used
Packaging
Copper wire is supplied on coils or spools by weight, in the gauge, finish (bare or tinned) and construction (solid or stranded) specified. Confirm all four before ordering.
Common Questions
What is tinned copper wire used for?
Tinned copper wire is used where improved solderability or extra corrosion resistance matters, such as marine electrical work or humid-environment installations, since the tin coating protects the copper surface and eases soldering.
