» 70/30 Copper Nickel (Cu/Ni) Seamless Tubes Useful information

Copper Nickel:

Cupronickel or copper-nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Cupronickel is highly resistant to corrosion in seawater, because its electrode potential is adjusted to be neutral with regard to seawater. Because of this, it is used for piping, heat exchangers and condensers in seawater systems, as well as marine hardware.

Chemical Element
Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color.

Symbol: Cu
Electron configuration: [Ar] 3d10 4s1
Melting point: 1,085 °C
Formula: Cu
Molar mass: 63.546 g/mol
Atomic number: 29
Atomic mass: 63.546 ± 0.003 u
