Can Aluminium be blued?
Bluing only works on steel, cast iron, or stainless steel parts for protecting against corrosion because it changes iron into Fe3O4; it does not work on non-ferrous material. Hot bluing should never be attempted on aluminium, as it reacts violently with the caustic salt bath, potentially causing severe chemical burns.
