The hidden trade-offs between copper and aluminum electrical wiring
In short: While both metals conduct electricity, they offer distinct advantages in weight, cost, and durability. This video explores why aluminum became a residential staple in the 1960s and why it remains essential for large-scale power distribution today.
The choice between copper and aluminum is rarely about which metal is 'better' in a vacuum, but rather which is appropriate for specific applications. Copper is often preferred for its reliability and conductivity in smaller settings, while aluminum is valued for its lighter weight and lower cost in massive distribution systems.
During the 1960s, aluminum gained popularity in residential homes, eventually developing a reputation for overheating and fire hazards. The video examines these historical issues alongside modern uses to determine how the material's properties dictate its role in our electrical infrastructure.
