Our Copper Nickel 70 / 30 One End Threaded Nipple can be utilized up to 700 Degree F for ASME code heat exchangers and unfired pressure vessels. Our Cu-Ni 70 / 30 Both End Threaded Nipple falls into the moderate to poor machining ability category due to its durability. The corrosion resistance and strength of Cupro Nickel 70 / 30 Concentric Swaged Nipple are improved by the addition of manganese, iron, niobium, and or chromium. These Copper Nickel 70 / 30 Eccentric Swaged Nipple is also used in desalination industry, marine engineering, extensively used in the chemical, petrochemical and electrical industries.

Cu-Ni 70 / 30 Concentric Nipple was developed specifically for seawater service over decades ago, initially for condensers and piping systems. Good thermal conductivities and ductility down to cryogenic temperatures are also important features of these Cu-Ni 70 / 30 Hex Nipple in their range of applications.
