The OK Tigrod 19.12 is a continuous, solid, Cu-Ni wire for welding similar alloys like 90Cu10Ni, 80Cu20Ni, and 70Cu30Ni. The addition of nickel not only strengthens the weld metal but also significantly improves corrosion resistance, particularly in saltwater. This ensures that the welds are not only durable but also resistant to the harshest of environments. The alloy is used for the overlay welding of steels and is widely used for welding Cu-Ni components for desalination plants.
