Each metal material has its own characteristics. Copper wire and aluminum wire have their own advantages and disadvantages, and their fields of usage are also different. Aluminum wire is more suitable for high-voltage lines. On high-voltage lines, the advantage of aluminum wire is obviously higher than that of copper wire. However, the use of wires in home has an obvious advantage over copper wires. Therefore, it is better to understand the characteristics of metal wires, act according to circumstance, make full use of it.
The difference between copper wire and aluminum wire are mainly as follows:
Color difference: the color of the copper wire is purple, and the color of the aluminum wire is grayish white.
Resistance difference: The resistance of copper wire is smaller than that of aluminum, and the conductivity of copper wire is better.
Density difference: The density of copper wire is larger than that of aluminum wire, and the copper wire is heavier.
