Specification:
CUNI is an alloy of copper that contains nickel and strengthening
elements, such as iron and manganese. Despite its high copper
content, cupronickel is silver in colour.
Due to the specific properties of nickel and copper alloys, they
are applied in various domains of industry e.g. mint industry,
armaments industry, desalination industry, marine engineering,
extensively used in the chemical, petrochemical and electrical
industries.
Cupronickel is highly resistant to corrosion in seawater because
its electrode potential is adjusted to be neutral with regard to
seawater. For this reason, it is used for piping, heat exchangers
and condensers in seawater systems, marine hardware, and sometimes
for the propellers, crankshafts and hulls of premiumtugboats,
fishing boats and other working boats.
