Why is Copper the #1 Choice for Electrical Connectors

 · Copper does not rust, but will produce a greenish patina called copper oxide. Unlike rust, however, this covering actually protects the metal from further corrosion and doesn't interfere with conductivity. How does aluminum wiring compare to copper? While aluminum can be used for electrical needs, copper is better in a number of ways.
