Copper lugs, aluminium lugs, bio metal lugs, stainless steel lugs

At that time, most electrical professionals were still learning about the larger coefficient of thermal expansion of aluminum compared to that of copper. The result was aluminum-bodied lugs used to terminate copper wire operated successfully, while copper-bodied lugs used to terminate aluminum wire failed. Three entire series of branch circuit device termination types were tried and failed: copper (C), copper/aluminum (CU/AL), and copper/aluminum/revised CU/ALR) before a workable design, copper/aluminum/rev.

II (CO/ALR) was achieved. Larger aluminum wire sizes terminated in copper lugs almost always presented problems, while the use of aluminum-bodied lugs reduced those problems, except when moisture entered in the formula.
