What is a C70600 copper nickel tube?
UNS C70600 is a 90% copper and 10% nickel alloy with tiny traces of other elements such as iron and manganese.
C70600 copper-nickel is a copper-nickel alloy formulated for primary forming into wrought products. CW352H is the EN numeric designation for this material. C70600 is the UNS number. Additionally, the EN chemical designation is CuNi10Fe1Mn. The British Standard (BS) designation is CN102. And the common industry name is Cupronickel 10.
