Why Tinned Copper Wire is better than Bare ones?

Copper wires that are available in the market today are either bare wires, insulated with nickel or tin or bunched copper wires. The bare wires are rated under the regular bare 12 gauge copper wire.

We take a close look at how bare copper wires are different from the tinned ones.

Bare copper is a great choice in industries concerned with the manufacturing of electrical equipments and associated appliances and products. Car and domestic appliances are all driven by power connected by copper wires. Great conductivity doubled by extremely good anti-corrosion properties make copper wires made in bare form best option to be used in internal circuits as well as external relays used in transformers and over-head transmission lines. It has a fairly good tensile strength which means that it does not  get snapped in heavy rains or thunderous storms.  The durability is very promising and comes with good workable features. Bare copper wires are easy to draw and flatten and can be used with any other wires as well.

Bare copper wires are little susceptible to the damp conditions as there is no insulation protecting its outer surface. It can not be used in places that are constantly dipped in fluid or water. Oil sump tanks and marine machineries use tinned wires. These tinned wires are usually bunched or braided wires. Bare copper wires are not considered for use in motors that are constantly submerged under the oil sump tanks. Using them in submarines and oil reservoirs in offshore areas is also not feasible as they might not be able to sustain the varying water pressure and the salinity level. Tinned wires come into the picture where bare wires leave. Tinned copper wires are usually bundled in the forms of braids or bunches.

Tinned wires are manufactured by the process of electroplating. Copper wires are coated with Tin particles by electrolysis. The coating is uniform and blends without leaving any chemical residue. Tinned copper wires are used in specialty appliances and high-grade engineering units. They are less used with gold jewelry and cosmetic surgery to fix bones and cartilages. Tinned wires are used along with the nickel plated wires and also Monel.

Tin is an ideal companion that can be used with the copper wires. It boosts the properties of the copper wires and helps them last ten to twenty times longer in life. Tin does not corrode and oxidize when exposed to rain. The electroplating prevents the interior copper walls to retain their properties even when the insulation is tapered or broken from some part.

Tinned copper wires are priced higher than the bare ones, but the investment is worth as they are sure to sustain the device long. Tin plating definitely increases the life expectancy of the bare copper wires. In addition to the insulation, it adds more grace to its appeal. Excellent resistance to humidity is the best feature that these tinned wires offer in comparison to others.
