Which metal is characterized as non-ferrous?

Copper is classified as a non-ferrous metal due to its lack of iron content. Non-ferrous metals are not magnetic and do not rust like ferrous metals, which contain iron. This characteristic makes copper valuable in a variety of applications, particularly in plumbing and electrical systems, where its resistance to corrosion, ductility, and excellent conductivity are essential. While brass, which is an alloy of copper and zinc, also falls under the non-ferrous category, copper itself is a pure element that distinctly represents non-ferrous metals. On the other hand, cast iron and carbon steel are ferrous metals because they contain iron and are susceptible to rusting and magnetic properties.
