Compare copper conductors to aluminum conductors in terms of tensile strength. Which statement is true?

Copper has higher tensile strength than aluminum, making it a superior choice for applications where strength is a critical factor. Tensile strength refers to the maximum amount of tensile (pulling or stretching) stress a material can withstand before failure. Copper’s higher tensile strength means it can be drawn into thinner wires without breaking, which makes it more effective for many electrical applications that require durability and resistance to mechanical stress. Additionally, this property contributes to the overall robustness of copper wiring, making it suitable for various use cases, including high-stress environments.

The fact that aluminum is lighter and has some advantages in terms of weight does not affect copper's superior tensile characteristics, which are important for ensuring the integrity of electrical systems over time.
