Advantages 1.Low price Compared with pure copper wire, the price of copper- clad aluminum wire is much lower, which is also an important reason why it is widely used. 2.Good electrical conductivity Although the electrical conductivity of copper-clad aluminum wire is not as good as that of pure copper wire, the electrical conductivity of copper-clad aluminum wire is much better than that of aluminum wire, and in actual use, its electrical conductivity can also meet most of the needs. 3.The outer layer of copper coated aluminum wire is wrapped by copper, which can effectively prevent the corrosion of wire and cable and extend its service life. 4.It is very suitable for automotive amplifiers or subwoofers, and can also be used as a ground wire for wire installation. Used in many different applications such as indoor lighting, car radios, automotive, lighting, car speakers, power cords, 12v power inverters, ground wires, or welding cables. 5.The lower the gauge number, the thicker the cable. Thicker cable presents less resistance to current flow. our wire is 0 gauge.
