True or False: Aluminum wire is generally heavier than copper wire.

Aluminum wire is actually lighter than copper wire. When comparing the two materials, aluminum has a lower density, which means it weighs less for a given volume. This characteristic can be particularly important in utility work, where the weight of the conductors can affect the overall structure and tension on support systems. While aluminum may also be less conductive than copper, making it necessary to use a larger gauge to carry the same current, its lighter weight can provide advantages in installation and overhead applications. Thus, the statement that aluminum wire is generally heavier than copper wire is false.
