What Is The Difference Between CCA And Pure Copper Wire?

1. Different colors: the color of copper wire is generally purple-red, while the color of copper-clad aluminum wire is gray-white;

2. Different density: the density of copper wire is larger than that of copper-clad aluminum wire, so the weight of copper wire will be heavier in comparison;

3. Different flexibility: the flexibility of the copper wire is better, the shape is simpler, and the fatigue resistance is strong, and the copper-clad aluminum wire is very easy to break when it is bent;

4. Different uses: copper-clad aluminum wires are mainly used as conductors for coaxial cables and wire and cable conductors in electrical equipment; while copper wires are mainly used to manufacture wires, cables, brushes, etc.;

5. Different definitions: copper-clad aluminum wire refers to the cable with aluminum-copper core cable as the main body, and a certain percentage of copper layer is plated on the outside; and copper wire refers to the copper wire drawn with pure copper rod;

6. Different structure: copper-clad aluminum wire is a bimetallic wire composed of an aluminum core wire and a copper layer that is tightly wrapped around it; while the copper wire is silver-plated or drawn on high-quality oxygen-free copper;

7. Different resistivity: the resistivity of copper wire is small, generally 1.68 times smaller than that of aluminum wire, so the power consumption of aluminum wire is relatively large, and the heat generation is serious, which can easily affect the efficiency of electricity consumption;

8. Different stability: The stability of copper wire is better than that of aluminum wire, because copper-clad aluminum wire is easily oxidized when used, which leads to an increase in resistance, reduces the load capacity of the wire, and leads to the occurrence of safety accidents.
