Enameled Copper Wire clad aluminum is outside and copper is aluminum inside.

The enameled aluminum is externally insulated and the inside is aluminum.
The Enamelled Wire is only made of aluminum as a conductor, and the copper clad aluminum wire has the characteristics of copper and aluminum. It combines the excellent electrical conductivity of copper and the light weight of aluminum. The conductor material mainly has the advantages of electrical conductivity. Distinguish, the following is a comparison of conductor resistivity of Enameled Copper Wire, aluminum, and copper clad aluminum:

A copper-clad aluminum wire with a length of 1 mm and a cross-section of 1 mm 2 has a resistivity of 0.02676 Ω·mm 2 /m at 20 ° C.

1 meter long aluminum wire with a cross-sectional area of 1 square millimeter, the resistivity at 20 ° C is 0.0294 Ω · mm 2 / m

A 1 m long copper wire with a cross-sectional area of 1 mm 2 has a resistivity of 0.0177 Ω·mm 2 /m at 20 ° C.
