Cupro Nickel vs. Copper - What is the Difference?

Have you ever wondered what the difference is between cupro-nickel and Copper? Both metals are commonly used in various industrial applications, from plumbing to electronics. But what sets these two metals apart from one another? Let’s look at some key differences between cupro-nickel and Copper.

Cupro Nickel

Cupro-nickel is an alloy of copper and nickel. It has a high resistance to corrosion and is often used in marine applications. Cupro-nickel is also known for its strength and durability.


Copper is a pure metal that is often used in electrical applications. It is also a very soft metal, which makes it susceptible to damage. Copper is also known for its ability to conduct heat and electricity.

Difference Between cupro nickel and copper

One of the biggest differences between cupro nickel and copper is their properties. Cupro nickel is much more resistant to corrosion than copper, making it the better choice for marine applications. Cupro nickel is also stronger and more durable than copper, making it a better choice for applications where strength and durability are important.

The most apparent difference between cupro-nickel and Copper is their composition. Cupro-nickel is an alloy made up of 90% copper and 10% nickel, while pure Copper is composed of pure Copper. This small difference in composition gives each metal properties that make them ideal for different types of applications.

For example, cupro-nickel has a higher resistance to corrosion than pure Copper due to its higher nickel content. This makes it an ideal choice for applications where corrosion resistance is necessary, such as plumbing systems or marine environments. It also has better thermal conductivity, making it a perfect choice for heat sinks or other high-temperature applications.

On the other hand, pure Copper offers better electrical conductivity than cupro-nickel because it lacks the impurities found in alloys like cupro-nickel. This makes it an ideal choice for electrical wiring and electronic components where low electrical resistance is important. Pure Copper also has higher ductility than alloys like cupro nickel, which makes it easier to shape into complex shapes or thin wires without breaking or cracking.


Cupro Nickel and Copper have unique advantages and disadvantages that make them suitable for different applications. Cupro Nickel offers superior corrosion resistance and thermal conductivity but lower electrical conductivity compared to Copper, while Copper provides better electrical conductivity with slightly lower ductility than Cupro Nickel. Understanding the differences between these metals will help you determine which type of metal best suits your application needs!
