ERNi-Cl (Nickel 99)

< CLICK HERE for additional information on this alloy >

ERNi-CI Nickel alloy 99 is used for TIG and MIG welding of cast iron.  This wire is extensively used to repair gray iron castings.  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 is recommended during welding.
