  The difference between bare copper wire and tinned copper wire
 
The first: different appearance.
Bare copper wire  is a copper wire drawn with a pure copper rod. The material is single.There is  copper metals on the surface and inside. The appearance used to be yellow, and the color is dark and light due to the purity of copper. In terms of physical properties, the bare copper wire is soft and has excellent conductivity.
The second one:  In terms of different Physical Properties.
The bare copper wire is soft and has excellent conductivity, Compared with bare cooper wire ,tinned cooper wire has good conductivity,stronger corrosion resistance and oxidataion resistance, and can greatly prolong the weak current.

Tinned copper wire refers to a thin layer of metal tin coated on the surface of the copper wire. Tinned copper wire has soft material and good conductivity. Compared with bare copper wire, its corrosion resistance and oxidation resistance are stronger, which can greatly prolong the service life of weak current cable.


Tinned copper only has a thin tin protective film than pure copper, and tin can form a tin oxide film in the air, which can effectively prevent further oxidation. When the copper wire is exposed in the air, it will oxidize and produce a thin layer of copper green on the surface. The conductivity of the copper wire producing Copper Green will be very poor and increase the resistance. Tinned copper has good corrosion resistance, and has a certain strength and hardness to prevent the insulation rubber from sticking, the wire core from blackening and brittle, good formability and easy to solder.

The third Difference: different processes,   Bare copper wire is copper wire drawn with pure copper rod, and the material is single ,there are many kinds of tinned copper wires ,including the most common bare cooper wire,tinned copper wire an copper -clad aluminum wire. The bare copper wire is an ordinary copper wire, also known as environmental protection copper wires. These three kinds of copper wires are unclear to many people,especially whether the bare copper wire or tinned copper wire is better.
Is the tinned copper wire better than bare copper wire.?

The environmental protection bare copper wire is the ul1007 electronic wire, ul1015 electronic wire, ul1061 electronic wire and ul1571 electronic wire made of pure copper rod. The material is single. There is copper metal on the surface and inside. The appearance is color in the past, and the color is dark and light due to the purity of copper. In terms of physical properties, the bare copper wire is soft and has excellent conductivity.



The process of tinned copper wire is slightly more complicated than bare copper wire, such as ul1007, ul1015, ul1061, ul1571, ul1095, ul1430 electronic wire, UL color flat wire, UL2651 gray flat wire, UL2468, UL terminal wire, UL wire, UL flexible flat wire, PE wire, ul1332, ul1333, ul3132, ul3135, ul3239, ul1672 double-layer insulated wire, ul20080 flexible flat wire, heat pipe, Teflon pipe, silicone pipe, After the pure copper rod is drawn into wire, a thin layer of tin is plated on the surface of the copper wire by hot-dip tinning process to form tinned copper wire. The appearance of this wire is silver because tin is a silver metal.
