What is a Non Ferrous Metal?

Non ferrous metal doesn’t contain any iron on its composition. These metals are more expensive compared to ferrous metals because of its excellent properties. It includes being non-magnetic, lightweight, and more.

Non ferrous metals are also recyclable. These metals are less time-consuming and easy to recycle compared to ferrous metals. It can be recycled through re-casting and re-smelting.

This metal is widely used for different applications including a wide variety of sheet metals. The main composition of non ferrous metals includes carbonates, silicates, and sulfides.

What is a Non Ferrous Metal
Brief History of Non Ferrous Metals

Brief History

Non ferrous metals are among the first metals utilized by humans. Therefore, these metals have long and significant history. Early humans used non ferrous metals for metallurgy since it does not corrode easily.

One of the earliest non ferrous metals used by humans around 4500 to 3300 BCE was the copper. Hence, marked transition to the Bronze Age. Within this age, people have began to mix copper with tin to create bronze. Bronze is commonly used in this era for tool and weapon production.

In this modern day, non ferrous metals have become part of the integral society such as modern technology, electronics, aviation, and more.

Non Ferrous Metal Properties

These metals offer a lot of excellent properties that make them desirable for different commercial, industrial, and residential applications. Non-ferrous metals share common properties including:

  1. Superior resistance against rust and corrosion.

Since non-ferrous metals do not contain any iron in their composition, these metals can offer excellent rust and corrosion resistance. Thus, making it ideal for the production of roofs, gutters, and other products that will be exposed to harsh elements.

  1. Non-magnetic properties.

Without the addition of any iron to it, non ferrous metals are non magnetic making it perfect for electronic and wiring applications.

  1. Lightweight

The disparity of the carbon content makes most of the non ferrous metal lightweight compared to ferrous metals. However, there are also non ferrous metals such as tungsten and lead that are heavier than ferrous metals.

  1. Price

Before using non-ferrous metals for your project, take note that it is more expensive than ferrous metals. Below are the main reasons why these metals are costly.

  • Demand and supply. These metals are costly to acquire since their demand is a bit higher than the supply.
  • Most industries such as engineering, automotive, aerospace, construction, and more are using these metals even in its limited supply, thus making it more expensive.

      5. Recyclability

All types of metals are highly recyclable. However, non ferrous metals have a lesser risk of degradation even when severally recycled. It is also capable of retaining its chemical properties during the recycling process.

Additionally, since the supply for non ferrous metals are limited, it is very important to recycle these materials. Recycling these metals also helps in reducing waste, decreasing gas emissions, protecting the environment, and saving energy.

Different Types of Non Ferrous Metals and Its Example Application


Due to its lightweight and easy to machine properties, aluminum is considered among the most important types of non ferrous metals. This is also commonly used as an alloy’s base metal. Aluminum is also a cost-effective choice when it comes to CNC machining.

Additionally, aluminum is also an excellent conductor of electricity and heat. It also offers superior ductility and malleability. Common applications of aluminum includes:

  • Airplanes
  • Automotive parts
  • Yachts
  • Drink cans
  • Sauce pans

Nickel is also a type of non-ferrous metal with silvery color. It has properties including high temperature resistance, toughness, and corrosion resistance. In spite of its excellent properties, nickel has less applications than other non ferrous metals.

If copper is alloyed with other elements, it can provide superior chemical and mechanical properties that makes it ideal for different applications such as:

  • Cryogenic equipment production
  • Hot-section of marine, automobile, and airplane equipment
  • Armor plating
  • Pipes
  • Producing nails

Silver is a soft, shiny, and lustrous metal. It offers a wide range of properties including corrosion resistance, good malleability, excellent electrical conductivity, very low contact resistance, and superior thermal conductivity. Common applications include:

  • Solar technology
  • Electronics
  • Brazing
  • Soldering
  • Engine bearings
