Due to their excellent resistance to sea water, these alloys are used in maritime environments, ship-building and valve technology.
These are Copper-Nickel alloys with good resistance to hot sea water and high rates of flow.
Vernicon excels thanks to its special corrosion resistance, as well as a very low temperature coefficient of resistance.
