Silver Plating for Copper and Copper Alloys:

Silver - Silver is quite soft and malleable (easily shaped).. With the exception of gold, it is the most malleable and ductile (able to be drawn into very thin wire) of all metals. Silver is harder than gold but softer than copper. It is quite resistant to corrosion and does not oxidize easily. Of all the metals, it is the best conductor of electricity. When silver is plated over copper there can be an accelerated corrosion of the copper at pinholes or breaks in the silver plating. It is then susceptible to the formation of cuprous oxide when stored or used in a moist or high humidity environment. The corrosion is known as "red plague" and is identifiable by the presence of a brown-red powder deposit on the exposed copper. Due to this possible corrosion, it may be wise to consider an insulation over the silver-plated copper wire, such as Teflon. Silver plated copper wire has applications in the medical field. Silver plating over oxygen-free copper reduces the resistance of the copper, thus enhancing audio and video cables and wires. Silver plated Copper wire is available with different plating thickness from 5 - 200 g silver / kg of wire. Silver plated Copper wire is available in diameters from 0.020mm to 0.500mm (AWG 52-24) with all insulations and self-bonding enamels. We also make Bare Silver Plated Wire.
