Ferrous vs Non-Ferrous Metals

The Difference Between Ferrous and Non-Ferrous Metals

One of the most important categorizations is whether a metal is ferrous or non-ferrous. In order to understand why this categorization is important, we first need to understand the difference between ferrous and non-ferrous metals.

On the surface, the difference is blindingly simple. Ferrous metals contain iron, and non-ferrous metals do not. However, there’s much more to that distinction than a simple black and white definition. Some non-ferrous metals do contain iron, but only in trace amounts. If iron is the first, second, or third main component, the metal is usually categorized as ferrous. Any other amounts usually lead to the metal being categorized as non-ferrous. However, it goes beyond that. The different compositions and uses of ferrous and non-ferrous metals are vast. Let’s examine some of the main qualities apparent in ferrous and non-ferrous metals.

Qualities of Ferrous Metals


Iron and many types of steel are all common examples of ferrous metals. These ferrous metals are well-known and popular because of how long they last. As you can imagine, thanks to the durability of these composites, ferrous metals are often used in construction, pipelines, and even the creation of tools. Cast iron skillets are a great example of the durability of ferrous metals.

They Are Extremely Strong

When you look at the uses of ferrous metals, you’ll recognize many products that are associated with strength. Products such as railroad tracks and cars rely on this strength to do their jobs over many years.


Just because they’re sturdy doesn’t mean ferrous metals aren’t also extremely malleable, which means the metal can be shaped without cracking or breaking. Steel, for example, is just blended iron and carbon. However, by changing the amount of either ingredient or adding in a few other materials, steel can be transformed to become anything from the thick steel beams used in skyscrapers to shiny stainless steel.

Examples of ferrous metals include:

  • Mild steel – Used for general engineering and building purposes
  • Carbon steel – Used for the creation of tools
  • Stainless steel – A ferrous metal that resists rust due to the presence of chromium
  • Cast iron – Used for vehicle engines, utility hole covers and cooking applications
  • Wrought iron – Typically used in gates and fences

Qualities of Non-Ferrous Metals

They Aren’t Magnetic or Corrosive

Because they contain little to no iron, non-ferrous metals tend to be non-magnetic. This makes them very useful in jewelry, wiring, and electronics.

Another advantage of the lack of iron content is the resistance to corrosion. Non-ferrous metals tend to last for a long time because they don’t corrode due to rust over time. This makes them extremely useful in products that are exposed to the elements like water pipes and gutters.


One last advantage of non-ferrous metals is that they are malleable and lightweight. This makes the metal easy to shape into a finished product quickly. Because of this, they’re used in certain airplane parts and street signs.

Guarantee Flexibility

Non-ferrous metals have a limitless variety of uses. Copper and aluminum are used for their ability to conduct heat and electricity. Several non-ferrous metals make up the core components of most smartphones. Of course, metals like gold and silver have been used decoratively for thousands of years. Non-ferrous metals are fundamentally resistant to both corrosion and magnetism, making them obvious choices for many applications across many different industries.  

Examples of non-ferrous metals include:

  • Lead – Used in pipes, fuels, paints and batteries
  • Copper – Used for wiring, appliances, and vehicles
  • Silver – Used for jewelry, cutlery, electrical contacts, and the creation of mirrors
  • Aluminum – Used in vehicles, appliances, power lines and food packaging
  • Brass – Used in screws, light fixtures, door knobs, as well as bath and sink fixtures
  • GoldUtilized for medical purposes, and is used in computers, electronics, and jewelry

Ferrous vs Non-Ferrous: So What’s the Major Distinction?

When it comes right down to it, the major difference between ferrous and non-ferrous metals is cost and availability. This is what affects how and when they’re used in producing everything from jewelry to automobile engines. Ferrous metals have the advantage here because the basic ingredients of ferrous metals — minerals like carbon and iron — are plentiful, easily obtainable, and often less expensive.

On the other hand, non-ferrous metals like gold and silver are exceptionally rare. That, combined with their relatively wide range of uses, tends to make non-ferrous metals more expensive. That’s why they’re often referred to as “precious metals.”
