Product Introduction

Copper Nickel 90/10 Pipes & Tubes are wrought alloys of copper and nickel is best chosen for the seawater environments as it contains 10 – 30 percent nickel. Also, some amount of iron and manganese are also added to increase the strength of corrosion resistance. It has high ductility and toughness which makes it a popular grade. It has excellent fabrication and welding properties. It is an inherent resistance to biofouling. It has some great properties which make it very appropriate to use in cryogenic temperature or very low temperatures. It has excellent antimicrobial properties. It is capable of killing 99 percent of germs within two hours.

Advantages of Copper Nickel Tubes
  1. Compared to other piping materials, copper nickel tubes offer several advantages that make them the first choice for many applications. Its superior corrosion and biofouling resistance is a significant advantage. Copper nickel alloys have excellent resistance to seawater and pitting, allowing them to maintain structural integrity and service life in marine and offshore environments.
  2. Copper nickel tubes have excellent thermal conductivity, ensuring efficient heat transfer in heat exchanger and condenser applications. This property enables energy efficiency and optimal performance in various industrial processes. The good mechanical strength and flexibility of copper nickel alloys also make them highly resistant to high pressure, stress and mechanical shock. This robustness ensures the reliability and durability of piping systems even under harsh operating conditions.
  3. In addition, copper nickel tubes are easy to fabricate, weld and form, making them easy to install and maintain. Notably, copper nickel is a non-magnetic material, making it suitable for applications where magnetic interference needs to be minimized. A perfect combination of corrosion resistance, thermal conductivity, mechanical strength and easy processing. White copper is a versatile and reliable piping material in a wide range of industries.
