Copper vs. Aluminum Wiring: Which to Use? | DoItYourself

Copper doesn't undergo the same extreme expansion and contraction cycles as aluminum so it is a more stable material to use. Due to its high ductile properties, copper can be formed into very fine wire, making it more versatile. Copper has high tensile strength as well, so it can undergo extreme stress but show minimal signs of wear and tear.
