Metals can be classified as either ferrous or non-ferrous. So what is the difference between ferrous and non-ferrous metals? It is the most frequently asked questions.
Shortly speaking, ferrous metals and alloys contain iron while non-ferrous materials do not.
Ferrous metals include mild steel, carbon steel, stainless steel, cast iron, and wrought iron. These metals are primarily used for their tensile strength and durability, especially mild steel which helps hold up the tallest skyscrapers and the longest bridges in the world. Besides, most ferrous metals also have magnetic properties, which make them very useful in the creation of large motors and electrical appliances. Most importantly, ferrous metals make up the most recycled materials in the world.
Non-ferrous metals include aluminum, brass, copper, nickel, tin, lead, and zinc, as well as precious metals like gold and silver. While non-ferrous metals can provide strength, they are primarily used where their differences from ferrous metals can provide an advantage.
For instance, non-ferrous metals are much more malleable than ferrous metals. Non-ferrous metals are also much lighter, making them well-suited for use where strength is needed, but weight is a factor, such as in the aircraft or canning industries. Because they contain no iron, non-ferrous metals have a higher resistance to rust and corrosion. Finally, they are also non-magnetic, which makes them perfect for use in small electronics and as electrical wiring.
