Copper-Nickel Alloys
A broad family of copper-nickel alloys built for corrosion resistance in seawater and aggressive media. From the Navinic® 90/10 and 70/30 cupronickels to high-strength nickel-aluminium grades (K5, K7) and resistance / electronic grades (ARCAP, Constantan), these alloys combine weldability, machinability and reliability for marine, defense, aerospace and electronics.

Key characteristics.
Corrosion resistance
Excellent behaviour in salt water and aggressive media.
High mechanical properties
Nickel-aluminium grades reach high strength for structural duty.
Weldable & machinable
Readily welded and machined into complex components.
Broad range
From 90/10 & 70/30 cupronickels to CuNiAl and resistivity grades.
10 product lines, one chemistry family.
