Question: 1 / 400

Which of the following materials is commonly used in non-ferrous applications?

Steel

Copper

Copper is a material that is widely used in non-ferrous applications due to its excellent electrical conductivity, thermal conductivity, and resistance to corrosion. Unlike ferrous materials, which contain iron and are prone to rust and oxidation, copper does not exhibit these drawbacks. This makes copper an ideal choice for electrical wiring, plumbing, roofing, and heat exchangers, where performance is critical and exposure to moisture or environmental elements is common.

While other materials like steel and cast iron are ferrous and can be used in different applications, they do not possess the same non-corrosive properties or conductivity that copper does. Aluminum oxide, while non-ferrous, primarily serves as an insulating material rather than a structural or conductive material. Thus, copper stands out as a prime candidate for non-ferrous applications in various industries.
