We are one of the largest stainless steel, duplex 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.
C68700 (C687), copper-nickel has excellent corrosion resistance, especially in marine salt water environments. The main wrought copper-nickel alloys for seawater service contain 10% or 30% nickel. They also have important additions of iron and manganese, which are necessary for good corrosion resistance. Some of the main uses for C706 include copper-nickel fittings and condenser and exchanger housings.
As one of the biggest projects pipeline products supplier in China, YUHONG GROUP can supply a wide range of C68700 tubes in different specifications like ASTM B111. This specification establishes the requirements for ferrule stock and a seamless tube of copper alloys of a specified range of diameters.
UNS C68700 has particularly good corrosion resistance in seawater. C44300 and C68700 pipes have good corrosion resistance. C68700 is annealed in O61 temper. The minimum tensile strength is 345Mpa, and the minimum yield strength is 125Mpa.
C68700 Tube Density 8.33g/cm3, 0.301lb/in.3
Typical Applications for C68700 Aluminum Brass "Arsenic"
1. Industry: condenser tubes, evaporator tubes, ferrules, distiller tubes, heat exchanger tubes
2. C68700 aluminum brass tube is widely used in "seawater desalination plant"
