ERNi-CI MIG & TIG Welding Wire

Metals And Welding Specialities offers premium-quality AWS Class ERNi-CI MIG & TIG welding wires, engineered for precision and durability in demanding industrial environments. Designed with superior metallurgical composition, this nickel-based filler metal is specifically used for joining and overlaying cast iron components. The ERNi-CI wire exhibits outstanding crack resistance and provides a tough, ductile weld deposit that minimizes post-weld stresses. It ensures excellent machinability and is ideal for both repair and fabrication applications involving cast irons and dissimilar metals.

Manufactured under stringent quality standards, Metals And Welding Specialities ERNi-CI is classified as per AWS A5.14 specification and carries the UNS N08121 designation. This classification guarantees consistent mechanical properties and stable arc performance across different welding parameters. The wire’s chemical balance of nickel and iron delivers exceptional strength, thermal stability, and corrosion resistance. Its smooth arc transfer and minimal spatter make it highly efficient for MIG (GMAW) and TIG (GTAW) processes, ensuring neat and uniform welds even on difficult-to-weld base materials.

In applications where machinability and strength are equally critical, ERNi-CI performs exceptionally well. It is widely used for welding various grades of cast irons such as gray iron, ductile iron, and malleable iron. The filler metal also serves effectively for joining cast irons to steels and stainless steels, creating sound joints without compromising metallurgical integrity. Its high nickel content provides excellent resistance to thermal cracking, oxidation, and corrosion, even in fluctuating temperature environments.

Industries such as automotive, foundry, repair, shipbuilding, and machinery maintenance rely on Metals And Welding Specialities’ ERNi-CI filler wire for restoring worn or damaged parts. From repairing engine blocks, gear housings, and cylinder heads to resurfacing pump components, this wire ensures long-lasting, high-quality welds. It also minimizes the need for preheating and post-weld heat treatment, making it a practical choice for on-site repairs and maintenance operations.

Every batch of Metals And Welding Specialities ERNi-CI MIG & TIG wire undergoes rigorous testing to ensure it meets international welding standards. The filler wire offers superior wetting action, stable arc characteristics, and easy slag removal, making it suitable for both automated and manual welding setups. With our commitment to precision engineering and product reliability, Metals And Welding Specialities continues to be a trusted name among fabricators and maintenance professionals worldwide.
