One of the characteristics of aluminum conduit is that it________________.

Aluminum conduit is known for its lightweight nature, which is one of its most significant advantages. This lightweight characteristic makes it easier to handle and install, especially in overhead or large-volume applications where weight might be a concern. The reduced weight also translates to lower transportation costs and less structural support needed compared to heavier materials like steel, enhancing its usability in various construction and electrical settings.

The other options highlight traits that do not apply to aluminum conduit in the same favorable way. While bending aluminum conduits can be done, it often requires specialized tools to achieve consistent bends. High ground impedance is not a desirable quality in conduit materials, and aluminum does have a tendency to corrode under certain environmental conditions, although it’s often treated or coated to mitigate this issue. Therefore, the lightweight characteristic stands out as a key benefit of aluminum conduit.
