Which type of copper conductor has a higher tensile strength?

• A. Soft-drawn copper conductor
• B. Hard-drawn solid copper conductor
• C. Both have equal tensile strength
• D. Neither can be compared

Answer: (B)

Hard-drawn solid copper conductors possess higher tensile strength due to the specific manufacturing process they undergo. When copper is drawn into wire, the material experiences work hardening, which increases its strength. In the case of hard-drawn conductors, they are pulled through smaller dies, which increases the tensile strength while reducing ductility. This process results in a denser and stronger conductor, making it more resistant to pulling and breaking forces. In contrast, soft-drawn copper conductors are more malleable and flexible, which makes them easier to work with in applications requiring bending and shaping. However, their tensile strength is lower than that of hard-drawn conductors because they have not undergone the same level of work hardening. Thus, when comparing the two types of copper conductors, it is clear that hard-drawn solid copper conductors exhibit superior tensile strength.
