Copper Nickel Forged Fittings
What are the advantages of using Copper Nickel Forged Fittings ?
These products are composed of copper and nickel, with impactful inclusions of iron and manganese. Copper nickel forged fittings are best suited to high pressures and temperatures (800 to 900°C), exhibiting trustworthy performance in marine and chemical industries.
- Withstands erosion, biofouling, and ammonia in seawater
- Cupro nickel bushing resists chloride-ion stress cracking
- Have a high PREN of 37
- Can face non-oxidising acids and salts
- Copper nickel socket weld fittings resist impingement corrosion
- Durable, with long service life and negligible maintenance
CuNi threaded fittings also work in water desalination and power generation.

Which corrosion testing methods evaluate the corrosion resistance of Copper Nickel Forged Fittings?
Intergranular corrosion (IGC) and pitting resistance tests are mandatory for cupro nickel threaded fittings. Salt sprays, electrochemical processes, and visual inspection ensure fitment to challenging environmental conditions.
Copper nickel 70/30 forged fittings also undergo non-destructive assessments like ultrasonic testing to detect discontinuities, and corrosive damage. Careful monitoring during quality checks safeguards results from:
- Humidity
- Severe temperatures
- Impurities and pollution
- Contact with dissimilar or reactive metals

What are the thermal conductivity properties of Copper Nickel Forged Fittings?
Thermal conductivity, measured in watts per metre-kelvin, denotes the ability to conduct and transfer heat. A 90/10 Cuni socket weld union shows desirable thermal properties, boasting a conductivity of 17.5 W/(m·K) at 20°C.
In comparison, steel is a poor thermal conductor. The conductivity of Inconel is around 5.8, while Hastelloy comes in at 9.8 W/m-K.
An ASTM B467 UNS C71500 socket weld elbow, which uses a 70/30 copper-nickel constitution, has an even higher value of 29 W/(m·K). These favourable properties emanate from its constituents – nickel and copper – which are both good conductors of heat.
Thermal applications like heat exchangers, condensers, heat sinks, etc., covet these characteristics. A UNS C70600 DIN 2.0872 socket weld coupling retains ductility and conductivity at low temperatures.
