Copper Nickel

Copper Nickel is a high strength and corrosion resistant alloy

Copper Nickel (also known as Cupro Nickel/Kunifer) is an alloy widely used in Marine, Naval and Oil & Gas applications. These alloys have excellent corrosion resistance in sea water, low biofouling and good weldability. Material in copper nickel is ductile through its improved strength and corrosion resistance.

CuNi 90/10 mainly used in seawater systems for Naval, Commercial Marine and Oil & Gas applications.

CuNi 70/30 has a higher strength due to the increased nickel content and able to resist corrosion at high velocities in Naval applications.

Amari Precision Tubes produce straight cold drawn copper nickel tube as well as copper nickel tube components from CuNi 70/30 and CuNi 90/10 alloys.
