What are three types of copper conductors?

Copper conductors are classified by their mechanical state after the drawing process, which changes how flexible or stiff the wire is. Hard drawn copper has been drawn to a small diameter and becomes stiff and strong, making it good for rigid conductors and where shape retention is important. Annealed copper is softened through heat treatment, relieving work hardening so the wire becomes highly ductile and easy to bend and form. Medium drawn copper sits between these two extremes, offering a balance of strength and ductility for general-purpose use. Other terms in the options describe different ideas, such as material composition or cross-sectional shapes, which aren’t the standard way to categorize copper conductors by draw state. So, the three common copper conductor states are hard drawn, medium drawn, and annealed.
