Multiple Choice

On average, aluminum conductors are cheaper than copper conductors by what percentage?

Aluminum is cheaper than copper by about a quarter on average, because aluminum is a less expensive raw material. That roughly 25% price gap is a common rule-of-thumb the industry uses when comparing conductor costs. This cost advantage helps make aluminum a popular choice for many distribution applications, especially where long runs and larger sizes are involved. Keep in mind that while the material cost is lower, aluminum has higher resistivity and different mechanical properties, so for the same current rating you often need a larger cross-section, which can influence total cost and ease of installation. The 25% figure is a typical average, though actual savings can vary with market prices.
