What is Nickel Alloy Filler Wire?
Nickel alloy filler wires are mainly made from nickel and are alloyed with elements like chromium, molybdenum, iron, and copper, depending on the specific grade requirements. This unique composition gives them remarkable resistance to corrosion, oxidation, and high-temperature degradation. The weld metal they produce boasts high tensile strength, good ductility, and impressive toughness across a wide temperature range. These filler wires also show stable arc behavior, a low tendency for hot cracking, and strong metallurgical compatibility with nickel alloys, stainless steels, and various base metals.
