What is the copper nickel?

Copper nickel alloys (also referred to as cupronickel or cunifer ) are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. Copper Nickel has provided reliable service for decades while offering effective sea water pipe fittings system and oil pipe fittings solutions ,

The addition of nickel to copper improves strength and corrosion resistance while allowing the alloy to remain ductile. Other elements can be added to copper-nickel to increase strength, corrosion resistance, hardening, weldability and castability.

90-10 copper-nickel (ASTM B151 (466) UNS C70600), an alloy with 90% copper and 10% nickel, is the most commonly used alloy. It can be found in naval and commercial shipping, offshore oil and gas production as well as desalination and power generation.
