* Feature
Dissimilar welding applications include joining alloys to Nickel 200 and copper-nickel alloys.
Widely used in marine applications because of its good resistance to the corrosive effects of seawater and brackish waters.
Can be used for MIG overlay on steel after a first layer with nickel 208.
* Application
Marine
