Copper Nickel 90-10 Flanges – The Advantages of Using Machining Services for High-Quality Precision Parts

Copper Nickel 90-10 flanges are often used in marine engineering, oil and gas production, power generation, & other applications. These flanges are known for their excellent corrosion-resistant properties, thermal stability, & malleability. However, not all copper-nickel flanges are created equal, which is where machining services come in. In this blog post, we will explore the advantages of machining services for high-quality precision copper-nickel 90-10 flanges.

What is Copper Nickle 90-10 Flanges?

Copper Nickel 90-10 Flanges are pipe flanges made with copper & nickel alloy containing 90% copper and 10% nickel. These pipe flanges have good corrosion resistance in seawater, brine water, sea air, and other abrasive environments. They also possess high strength characteristics at elevated temperatures, making them suitable for marine applications. The Copper Nickel 90-10 Flanges are widely used in industries for their strength and excellent resistance to heat pitting corrosion, stress corrosion cracking, erosion corrosion, and various forms of corrosive attack. The minimal maintenance required and excellent dimensional stability make them ideal for use in industrial piping systems that must constantly adjust to changing pressures or chemical concentrations.

Advantages of Copper Nickel 90-10 Flanges Using in Machining Services for High-Quality Precision Parts

Consistent dimensional accuracy

Copper Nickel 90-10 Flanges are specifically designed for applications requiring higher strength and corrosion resistance than pure copper alloys. They provide exceptional dimensional accuracy and consistent performance, making them ideal for various high-pressure and temperature applications. The 90:10 Copper Nickel alloy is composed of 90% copper and 10% nickel, which creates an incredibly strong material with excellent corrosion resistance in seawater, acids, chloride environments, dilute organic acids/salts, alkalis, and many other media. Adding nickel to the copper base also provides improved thermal conductivity and enhanced mechanical properties relating to hardness & tensile strength. With its superior dimensional integrity and uniformity throughout all areas of the flange profile, COPPER NICKLE 90-10 ensures reliable long-term connections with repeatable performance without risk of leakage or distortion, even under extreme pressure or temperature fluctuations.

Improved Surface Finish

Copper Nickel 90-10 Flanges offer an improved surface finish compared to other flange products. This is because the base material for this flange type is composed of copper and nickel alloy. Copper offers excellent machinability with superior finishes, while nickel provides strength and corrosion resistance. The 90-10 ratio also adds malleability, making it easier to shape into desired shapes. These features make Copper Nickel 90-10 ideal for applications that require high-performance components, including offshore environments, desalination plants, paper mills, pulp & paper processing industries, etc. Furthermore, its easily machined surface allows for accurate size control during manufacturing, increasing product accuracy and consistency in repeat orders.

Faster turnaround times

Machining services offer faster turnaround times for copper-nickel 90-10 flange production than traditional methods. With CNC machines, it is possible to produce large quantities of parts quickly and efficiently. This can help reduce lead times, a critical advantage in industries such as marine engineering and oil and gas production, where downtime is costly.

Greater Freedom in Design

CNC machining also offers greater freedom in design for copper-nickel flanges compared to traditional methods. This is because CNC machines can work with various materials and produce complex shapes and features with high accuracy. With machining services, designers can optimize the performance of copper-nickel 90-10 flanges and improve their overall functionality.

Quality Control and Testing

Quality control and testing of copper-nickel 90-10 flanges are essential to ensure the safety, integrity, and longevity of any system in which they are used. Quality control begins with material selection and testing of raw materials for high standards that will yield a quality product. During manufacture, the flanges undergo several stages of inspection, including checks for conformance to dimensional specifications such as inner diameter, wall thickness measurements, etc., depending on the type. The surface finish should be checked for cracks or other defects, and dimensions must be exact enough to avoid gas/liquid leakage under pressure loading. Needle flame tests can also be performed to check whether structural flaws exist. Finally, pressure vessel tests may also be carried out along with non-destructive examination (NDE) techniques like X-ray fluorescence analysis or ultrasonic technique for detecting internal defects before it is shipped from the manufacturer’s end.


In conclusion, machining services offer many benefits for producing copper-nickel 90-10 flanges. Consistent dimensional accuracy, improved surface finish, faster turnaround times, greater freedom in design, and quality control and testing are some advantages. By working with a machining service provider, industries can obtain high-quality, precision copper nickel flanges that meet their requirements and exceed their expectations.
