〉201359ヂ In the earlier years of aluminum condensing coils, Arizona AC contractors tended to favor copper tube with fin coils. However, a change over may be taking place. No matter what other arguments are in place, unit cost remains a primary factor in any AC purchase decision. For example: Aluminum coils cost less to manufacture than copper

〉However, aluminum has only 60% the conductivity of copper. If the winding volume is increased by 40% to raise the aluminum conductivity to that of copper, it still leaves the aluminum coil weighing only 42% of the equivalent copper coil. Unfortunately, one cannot simply increase the winding volume of a transformer to make use of the aluminum foil.

〉On squirrel-cage induction motors, there is an important choice between utilizing a lower cost die-cast or fabricated aluminum rotor versus the more expensive copper bar rotor. Utilizing the wrong rotor construction for the application can either increase costs unnecessarily or lead to catastrophic failure.
