Which material is not listed as a pipe material in the group alongside steel, copper, brass, and aluminum?

The main idea is recognizing material categories for pipes. The group mentioned lists metal pipe materials: steel, copper, brass, and aluminum. Plastic is not a metal; it belongs to a different piping material family (like PVC, CPVC, PEX). Because of that, plastic does not fit with the metal options, making it the material that doesn’t belong in that group. Copper and aluminum are metals and fit the group, while plastic stands out as the non-metal option.
