Nickell 99 is a machinable cast iron rod and is preferred when the weld needs to be drilled, tapped, milled or machined in any way. AWS Requires a minimum of 85% Nickel in this alloy, typically XTRweld product is typically at least 99%.

APPLICATIONS

XTR Nickel alloy 99 is used for TIG and MIG welding of gray iron castings, cast iron and joining cast iron to mild steels, stainless-steel alloys and come copper alloys. It can also be used for overlay and build-up applications. Dilution from the casting influences the mechanical properties of the metal. Due to the high nickel content, the welds are readily machinable. A preheat and inter-pass temperature of at least 350°F (175°C) is required before welding on cast iron to minimize the potential for cracks during and after the weld cools.
