Product Details

Copper-nickel tube UNS C70400 has a copper content of not less than 92.4%.

Copper nickel alloys, also known as Cu-Ni, offers excellent corrosion resistance, especially in marine salt water environments. Copper nickel alloys that are generally chosen for sea water parts and service equipment contains 10 to 30 percent nickel.
Longda Metal produces C70400,C70600, C71500 and C71640 Copper Nickel pipes, which are commonly used in seawater piping due to its complete resistance to barnacles. Due to Its resistance of various sea organisms, this alloy makes seawater desalination, water systems, fire fighting systems, and similar applications very reliable.
These various alloys also have important additions of iron and manganese, which are necessary to maintain good corrosion resistance in the harsh environments.
