Non ferrous metals is anything EXCEPT cast iron/steel Examples of non ferrous metals are aluminum, brass, bronze, pewter, zinc, etc.

That said, there's no real reason a dye/penetrant-type crack detector couldn't be used on ferrous metals, although I would want to look for a system designed for use w/ferrous metal if that's what I was working with.
