Tinned Copper (Solid or Stranded)

Product Description:

Solid soft tinned copper wires are 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 100° C up to 150° C. At such temperatures the corrosion resistance of bare copper declines and the tin coating acts to protect the surface of the bare copper.

Single-strand conductors can be tin coated as soft, medium hard or hard wire. The standard minimum thickness of tin coating is 40 micro-inches.

Specifications:

The tin coating is applied in accordance with ASTM B33-81. Bare conductor prior to coating will meet ASTM B1-81, B2-82, or B3-74.
