Description
ERCuNi can be used for MIG overlay on steel after a first layer with Nickel 208. Dissimilar welding applications include joining copper-nickel alloys to Nickel 200 or nickel-copper alloys.. It can equivalent to: Oxford Alloy 67 FM 67, Techalloy 413.
Applications
ERCuNi is used for TIG, MIG, and oxyfuel welding of 70/30, 80/20 and 90/10 copper- nickel alloys. This filler metal can be used for MIG overlay on steel after a first layer with Nickel 208 (Filler Metal 61). Dissimilar-welding applications include joining copper-nickel alloys to Nickel 200 or nickel-copper alloys.
