Product Description
NACOBRE DENOMINATION: 71640

DESIGNATION: COPPER NICKEL  IRON-MANGANESE

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, steam condenser air ejectors and 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.

Copper nickel 70-30% 715 is one of the most corrosion resistant and durable of the copper-base alloys for condenser and heat exchanger tubes in sea water. In high pressure, high-temperature steam stations, copper nickel 70-30% tubes are used in feedwater heaters regardless of the type of tube used in the main condensers. The high allowable design

stress for this alloy qualifies it for this exacting duty.
