What is a quality associated with copper conductors compared to aluminum?

Copper conductors possess a higher conductivity compared to aluminum, which is a critical quality in electrical applications. This increased conductivity means that copper can carry electric current more efficiently than aluminum, allowing for smaller conductor sizes to achieve the same electrical performance. This characteristic is particularly vital in aerospace and other high-performance electrical systems where minimizing weight and maximizing performance is essential.

The difference in conductivity also influences other important factors such as voltage drop and power loss within the conductors. This makes copper a preferred material in situations where optimal electrical performance is required. In many applications, the benefits of using copper conductors often outweigh the downsides, such as increased weight and cost.

While copper is indeed heavier than aluminum and generally more expensive, these factors do not overshadow the primary quality of higher conductivity, which can result in more efficient designs and reduced energy costs over time.
