Why ERNiCu-7?

• No Preheat required, maximum interpass temperature 150℃ and no PwHT required
• 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
