Description: AFM NI-99 is designed for welding thin sections of cast iron to itself or to low
alloy and carbon steels. This all-position electrode is used where maximum
machinability is required. The weld deposits are ¡°soft¡± and can be drilled,
tapped, milled or shaped.
Applications: AFM NI-99 is especially suited for repairing porous or cracked castings and can be used to weld cast iron to itself or dissimilar metals.
