1.2 mm Mig Wire Ernicrmo-3 1.20mm

ERNiMo‑3 is a specialized nickel‑based welding filler metal conforming to the AWS A5.14 (also ASME SFA A5.14) standard, often referred to as "Alloy W." It is purpose-designed for welding nickel‑molybdenum alloys, particularly high-performance materials like Hastelloy® W, and excels in dissimilar metal welding, especially involving cobalt‑ and nickel‑based alloys used in high-temperature environments. The typical chemical composition of ERNiMo‑3 weld metal includes roughly 62.5 % nickel, 24 % molybdenum, 5 % chromium, and about 6 % iron, along with minor amounts of other elements such as carbon, silicon, and vanadium.This alloy matches AWS requirements: carbon ≤ 0.12 %, chromium between 4–6 %, molybdenum 23–26 %, iron 4–7 %, nickel balance, and allowable traces of other elements like copper, silicon, vanadium, and tungsten. ERNiMo‑3 delivers robust mechanical properties—with deposited weld metal showing tensile strength around 109,500 psi and elongation up to 42 % in some formulations—making it suitable for high-stress applications.It performs reliably up to approximately 1,800 °F, though its oxidation resistance diminishes beyond about 1,400 °F, and it's generally not recommended for continuous exposure beyond 750 hours in such conditions. Its primary applications lie in aerospace and gas turbine maintenance, especially for jet engine repairs, rotor component welding, and other high-temperature, high-stress environments. Additionally, ERNiMo‑3 finds use in welding dissimilar high-performance alloys, thanks to its compatibility and strong fusion with both nickel‑based and dissimilar substrates. In summary, ERNiMo‑3 (AWS A5.14 Alloy W) is a nickel‑molybdenum-chromium welding filler optimized for high-temperature, high-strength applications, particularly where aerospace-grade superalloys or dissimilar alloy junctions must be reliably welded under demanding service conditions.
