What is a C70600 copper nickel tube?
UNS C70600 is an alloy containing 90% copper and 10% nickel, with trace amounts of other elements such as iron and manganese.
C70600 copper-nickel alloy is a copper-nickel alloy specifically formulated for primary forming of forged products. CW352H is the EN number for this material. C70600 is its UNS number. Furthermore, its EN chemical formula is CuNi10Fe1Mn. The British Standard (BS) number is CN102. Its common industry name is Cupronickel 10.
C70600 copper-nickel pipe (CuNi 90/10) is a high-strength, corrosion-resistant pipe solution composed of 90% copper and 10% nickel, with trace amounts of iron and manganese added to enhance its resistance to seawater corrosion, biofouling, and durability. These pipes are widely used in marine, offshore, power generation, and industrial fields due to their excellent mechanical properties and long service life in harsh environments.
