The ECuNi Welding Electrodes are engineered with a unique copper-nickel composition, offering excellent resistance to seawater corrosion, stress cracking, and erosion. Their chemical stability makes them particularly valuable for welding copper-nickel alloys widely used in shipbuilding, desalination plants, and heat exchanger systems. Metals And Welding Specialities ensures these electrodes deliver a stable arc, smooth bead appearance, and low spatter, providing welders with ease of use and consistent quality results.
With ASTM B432 as the universal standard and UNS C71500 as its material designation, these electrodes offer long-lasting protection against localized corrosion in saline environments. Industries that depend on durability under harsh conditions choose Metals And Welding Specialities’ electrodes for joining and overlaying applications. Their ability to maintain mechanical strength while withstanding biofouling, pitting, and crevice corrosion gives them a distinct advantage over conventional consumables.
The unique coating on the ECuNi Welding Electrodes enhances slag detachability, reduces porosity, and ensures superior metallurgical bonding. This makes them highly efficient for use in fabrication and repair projects where precision and durability are critical. The electrodes demonstrate excellent toughness, ductility, and thermal conductivity, ensuring joints remain strong under fluctuating temperatures and pressures.
