C70600 Copper Nickel 90/10

C70600 Copper Nickel 90/10 is an alloy in the copper nickel family of alloys.  The alloy is extremely versatile known for its high heat transfer, ductility, and corrosion resistance.  Copper-nickel (also known as cupronickel) alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. They have provided reliable service for decades while offering effective solutions to today’s technological challenges. (copper.org)

Cupronickel or copper-nickel is an alloy of copper that contains nickel and strengthening
elements, such as iron and manganese. cupronickel is highly resistant to corrosion in seawater,
because its electrode potential is adjusted to be neutral with regard to seawater. Because of this, it is
used for piping, heat exchangers and condensers in seawater systems, as well as marine hardware,
and sometimes for the propellers, crankshafts and hulls of premium tugboats, fishing boats and
other working boats.

Condenser tubes of this alloy are giving long and dependable service at sea. It is also
highly satisfactory for tubes in evaporators, inter-after condensers, air ejectors of steam condensers
and in boiler feedwater heaters. This alloy is particularly desirable where high temperatures are
encountered. It has the property of forming protective films of corrosion products, making it particularly desirable for service where water velocities are high.
