GEN 418

GEN 418 Overview

GEN 418 is a nickel‐copper welding wire used for welding of Monel® 400, 404 and K500. It can also be used in dissimilar joining applications include nickel‐copper alloys, carbon as well as low alloy steel to Nickel 200. GEN 418 is commonly used in marine applications due to its excellent corrosion resistance against seawater.
