Copper Wire


Copper wire is coated with tin in order to keep its conductive characteristics while becoming much more resistant to corrosion by protecting it from the elements. It also provides much more strength and durability to the wire. Tinned copper wire can last up to 10 times longer than untinned wire. Because of its superior corrosion resistance and greater strength, tinned wire is preferable wherever the wire is exposed to water and other corrosive elements. It is used in overhead wire applications for subways, light and heavy transit, mine trains, buses, industrial cranes and marine projects, among others. It is also easier to solder, so it allows for stronger connections.

Annealed Bare Copper

Bare Copper Wire is normally defined as wire made up of copper metal consisting of a single conductor for electrical signals, distinguished from a copper cable where several Bare Copper Wires are band together into a common jacket. Annealed Bare Copper Wire is formed by hardening and subjecting copper to heating below its melting point to make it malleable. Annealed Bare Copper Wire is then made using these copper materials.

  • Annealing of copper wire makes it more ductile and reduces its hardness, making it more workable for different products.
  • The properties of Annealed Copper Wires are high malleability, kink-free, high electrical and thermal conductivity, highly flexible wires, Soft and annealed, highly conductive.
