ASTM B111/ASME SB111 C71500 O61 COPPER NICKEL ALLOY TUBE FOR CONDENSER

We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.

C70600 (C706) & C71500 (C715), Copper nickel offers excellent corrosion resistance, especially in marine salt water environments. The main, wrought copper-nickel alloys chosen for sea water service contain 10 or 30 percent nickel. They also have important additions of iron and manganese which are necessary to maintain good corrosion resistance. Some of the primary uses for C706 include copper nickel fittings (CuNi Fittings) as well as condensers and exchanger shells.

Overview

Copper Nickel alloy Tube has extremely well resistance to biofouling and marine corrosion, and possess good fabricability. Copper gains more strength and corrosion resistance when nickel is added to it. UNS C71500 copper nickel alloy has medium high strength and good creep resistance at high temperatures. This alloy is expensive in comparison with copper-aluminum alloys and other alloys with similar mechanical properties. C71500 copper-nickel is an alloy of copper, further classified as a copper-nickel . CW354H is the EN numeric designation for this material. C71500 is the UNS number. Additionally, the EN chemical designation is CuNi30Mn1Fe. The British Standard (BS) designation is CN107. And the industry name is Cupronickel 70/30.
