aluminum wire
Silver-toned electrical strand
Aluminum wire is electrical wiring made from aluminum rather than copper.
It was widely installed in homes during the 1960s and 70s when copper prices spiked.
Aluminum wire requires special connectors and outlets because the metal expands and contracts more than copper, creating loose connections that pose fire risks: The inspector flagged the aluminum wire as a concern.
