Is it okay to use aluminum wire in an electric circuit used for a kiln?

During the mid-70s there was a copper shortage, so aluminum wiring was used in thousands of homes. In some cases, the aluminum wasn't installed properly. It was connected to terminals designed for copper. This resulted in loose connections, overheating, and fires. People reported smelling burning wire insulation in their homes. Though aluminum wiring may be adequate when installed properly, copper wire is a better conductor. Please stick with copper.
