ASTM B111 C70600 Copper-Nickel Alloy Seamless Tube CU-NI Alloy
We are one of the largest stainless steel, duplex steel and alloy steel pipe manufacturers in China. After more than 20 years of development, we have accumulated a large number of customers all over the world, and Yuhong products have also won unanimous praise from customers.
C70600 (C706) and C71500 (C715), copper nickel has excellent corrosion resistance, especially in marine salt water environment. The main forged copper-nickel alloys selected for seawater service contain 10% or 30% nickel. They also add important iron and manganese, which are necessary to maintain good corrosion resistance. Some of the main uses of C706 include CuNi Fittings and condenser and exchanger housings.
