A non-ferrous metal is any metal or alloy that does not contain a significant amount of iron (Fe).

The term "ferrous" comes from the Latin word ferrum, meaning iron, so "non-ferrous" simply means "without iron."

This distinction is important because the absence of iron gives these metals a unique set of properties that make them highly valuable, especially for recycling.

 

Key Characteristics of Non-Ferrous Metals:

 

CharacteristicDescription
 

No Rust

They do not contain iron, so they do not produce rust (iron oxide) when exposed to moisture. However, they can still corrode in other ways (e.g., copper turning green).

Non-Magnetic
The lack of iron makes most non-ferrous metals non-magnetic, which is useful in electronic and sensitive applications.
 

Lightweight

Many non-ferrous metals, like aluminum and titanium, are significantly lighter than ferrous metals (like steel).

High Conductivity
They often have superior electrical and thermal conductivity, making them excellent for wiring and heat exchangers.
 

Malleable/Ductile

They are often softer, more malleable (can be hammered into sheets), and more ductile (can be drawn into wires).
 

High Value

Non-ferrous scrap metals are generally more valuable to recycle than ferrous metals due to their specialized properties and relative scarcity.
