It can be the most difficult task to select something that adds strength to your machinery. We understand the complexity and hence present you a small guide that makes it easier to choose between Cupro Nickel Tubes and Brass Tubes. They both mostly serve the common end goals, but at some point there might be some differences.

Let’s read how Cupro Nickel Tubes and Brass Tubes are different.

What is Cupro Nickel Tube?

To give the end product of Cupro Nickel Tubes, many metals are used, such as a combination of copper and nickel with a small amount of iron and manganese. Mostly iron and manganese are used to give strength and corrosion resistance. Usually, cupro nickel tubes are perfect for industries that need strength and seawater corrosion resistance.

Main features of cupro nickel tubes

  • High corrosion resistance
  • High thermal conductivity
  • Higher resistance to biofouling
  • Mechanical strength and durability
  • Low maintenance cost

Where can you use it?

  • Marine industry
  • Heat exchangers
  • HVAC systems
  • Power generation plants
  • Automotive and aerospace industries

What is Brass Tube?

Everyone is aware of how brass is made, but let us tell you that brass is made of copper and zinc. However, you can add a different amount every time in the composition that affects its mechanical properties. As per our experience, brass is widely used in plumbing, industrial, or decorative purposes.

Main features of brass tubes.

  • Good corrosion resistance
  • High machinability
  • Attractive appearance
  • Cost effective
  • At Sneh Metals Alloys you can find a variety of brass products

Where can you use it?

  • Plumbing and water distribution
  • Musical instruments
  • Decorative items
  • In gas and fluid transportation
  • HVAC and refrigeration systems

As we have read about cupro nickel tubes and brass tubes, their main features, and where you can use them, now let’s read about some of the key differences of these two.

  • Composition: Cupro nickel tubes are made of copper, nickel, iron and manganese. Whereas brass tubes are made of only two materials, and which are copper and zinc.
  • Corrosion resistance: Usually, people use cupro nickel tubes for machinery that gets frequent connection with sea water because of their corrosion resistance quality. But one can not use brass tubes for sea water. They are not just ideal for seawater machinery.
  • Strength and durability: When it comes to strength, it is difficult for brass tubes to beat cupro nickel tubes. Cupro nickel tubes have higher strength and durability.
  • Thermal conductivity: In thermal conductivity, also cupro nickel tubes beat brass tubes. They are in excellent quality and used widely for thermal conductivity.
  • Machinability: In the machinability aspect, we can say that brass tubes have beaten cupro nickel tubes. They are perfect for machinability, whereas cupro nickel tubes are moderate.
  • Cost: If you don’t want to spend much, then you must select brass tubes. Brass tubes are a perfect, cost-effective option for your machinery. Cupro Nickel Tubes are a bit expensive.
  • Use cases: You can use cupro nickel tubes in Marine industrial and high temperature applications. They are perfect for these industries. Whereas, brass tubes are perfect for industries like plumbing, decorative, and general purposes.

As we have come across all the factors now, let’s read the different factors you need to consider before choosing.

  • Environment
  • Budget
  • Corrosion Resistance
  • Machining and fabrication

These are the main 4 factors you have to consider before buying cupro nickel tubes or brass tubes. 

Conclusion

We hope this guide has helped you in your confusion regarding cupro nickel tubes and brass tubes. Usually, it depends on your application, usage, budget, as well as environmental factors.
