What Is Copper Nickel Forged Fittings?

The copper nickel forged fittings are produced with 90% copper and 10% nickel content. These fittings also possess other strengthening alloys of iron and manganese. Cu-Ni bushing are employed to connect piping equipment of different configuration. These fittings characterize the fluid and gaseous flow in the system. The copper nickel threaded fittings showcase good corrosion resistance properties. Cuni forged fittings work well in marine setups. These fittings have enhanced resistance to stress-corrosion cracking and pitting by acids. The 90/10 copper nickel threaded elbow possess enhanced toughness and have high ductility in the system. These fittings have good fabricability and are very reliable. Our Cu-Ni forged fittings products conforms various international standards such as ASTM B151 and ASME B16.11. These fittings generally used in many application such as chemical, engineering, construction, gas and shipbuilding, petroleum industries.
