Which of the following metals is likely to be classified as non-ferrous?

Copper is classified as a non-ferrous metal due to its lack of iron content. Non-ferrous metals are those that do not contain significant amounts of iron, making them resistant to rust and corrosion. Copper is well-known for its excellent conductivity of heat and electricity, making it widely used in electrical wiring and plumbing applications. Additionally, its malleability and ductility allow it to be shaped into various forms, further contributing to its versatility in engineering and manufacturing.

Steel and cast iron, on the other hand, are both classified as ferrous metals because they contain iron as a primary component. This presence of iron gives them properties that include strength and hardness but also makes them susceptible to rust if not properly protected. Bronze, while primarily an alloy of copper, often contains tin or other elements and can be considered non-ferrous as well; however, copper is the more straightforward example of a non-ferrous metal in this context.
