N4 Nickel Electrode Wire 1.2mm-3.2mm

Introduction to N4 Nickel Electrode Wire
N4 Nickel Electrode Wire is a high-purity nickel welding wire (≥99.9% Ni) designed
for TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding applications. With
diameters ranging from 1.2mm to 3.2mm, this electrode wire provides exceptional
corrosion resistance, thermal stability, and superior weldability, making it ideal
for demanding welding tasks in chemical, marine, and high-temperature industries.

N4 nickel electrode wire is widely used for joining pure nickel, nickel alloys, and
dissimilar metals, offering strong, ductile, and oxidation-resistant welds. It is
an excellent choice for welding nickel-based heat exchangers, pressure vessels, and
industrial pipelines.
