Copper has excellent physcial, thermal properties and electrical conductivity. Copper is easily soldered, welded and plated for corrosion resistance.
Gold plated pure copper is used when electrical condutivity is crucial and its application is critical to maintaining a stable resistance with minimal variation over the wire length.
