Is IMC made of steel only, or is aluminum, or both? Me and another journeyman had this argument today.

You know the code book can solve many disagreements.

RMC can be, steel, stainless steel, aluminum, silicon bronze.

Rigid Metal Conduit (RMC). A threadable raceway of circular cross section designed for the physical protection and routing of conductors and cables and for use as an equipment grounding conductor when installed with its integral or associated coupling and appropriate fittings. RMC is generally made of steel (ferrous) with protective coatings or aluminum (nonferrous). Special use types are silicon bronze and stainless steel.


On the other hand IMC is steel.
