Aluminum wiring became prevalent in residential construction beginning in the 1960s due to a combination of factors, including the rising cost of copper and the desire for more economical building materials. During this time, many builders and contractors opted for aluminum wiring as a cost-effective alternative to copper without fully understanding the long-term implications, such as higher potential risks of overheating and deterioration at connections.

The use of aluminum wiring gained further traction as housing demand surged during this decade, particularly in suburban areas. However, as the use of aluminum wiring increased, so did awareness of safety concerns, leading to regulatory and industry responses in subsequent years. The introduction of stricter electrical codes and guidelines in the following decades ultimately influenced a decline in aluminum wiring's popularity.

Understanding this context is essential for grasping the historical timeline of electrical wiring in residential buildings and its implications for safety and inspections.
