How does the tensile strength of aluminum compare to hard drawn copper?

The tensile strength of aluminum is indeed about half that of hard drawn copper. This means that when considering materials for applications such as electrical wiring or structural components, aluminum has a lower ability to withstand tension compared to hard drawn copper. This characteristic is crucial, especially in industries like electrical and construction, where the strength-to-weight ratio plays a significant role in performance.

In practical applications, while aluminum may be lighter than copper, the trade-off comes with a lower tensile strength. This is essential for linemen to understand when selecting materials for various tasks, ensuring they choose the appropriate metal based on strength requirements and intended use.
