Identification method of enameled copper wire:

Most enameled copper clad aluminum wires are soft copper wires, and the identification method is very simple. One end of the copper wire is burned by the external flame of the lighter. Because the melting point of the aluminum wire is lower than the melting point of the copper wire, if you use copper-clad aluminum wire, this part will quickly become ashes by the flame and nothing will be left. However, after the pure copper burns, the copper wire shrinks quickly, leaving a small ball on the wire.

Comparison of enameled copper clad aluminum wire;

Compared with pure copper wire, enameled copper-aluminum wire has the advantages of good conductivity, light weight, obvious economic benefits, flexible structure and easy operation. The length ratio of the same steel wire under the weight of the warp is 2.45:1. Purchasing 1 ton of copper-clad aluminum wire is equivalent to purchasing 2.45 tons of pure copper wire, which has the huge advantage of saving costs.

Compared with pure aluminum wire, enameled copper aluminum wire has higher conductivity, higher tensile strength and elongation, and good weldability: copper clad aluminum wire has the same weldability as pure copper wire. Because its surface is coated with a layer of pure copper concentrically, the mechanical properties and applicability of the product are greatly improved.

The identification of Round Enameled Copper Wire is the same.
