**Adrian Nickel Alloys** stands out as a reliable supplier of **AWS Class ERCuNi MIG and TIG filler welding wire and rod**. We provide top-notch copper-nickel welding consumables that excel in tough marine, offshore, and chemical processing environments. Whether you’re welding similar Cu-Ni alloys or tackling dissimilar joints, ERCuNi wire and rods are designed to deliver outstanding corrosion resistance, especially in saltwater and brackish conditions.
**AWS ERCuNi** is a **copper-nickel alloy filler metal** that consists of about **69% copper, 30% nickel**, along with trace amounts of iron and manganese to boost strength and corrosion resistance. This filler metal is perfect for both **GMAW (MIG)** and **GTAW (TIG)** processes and is commonly used for welding **90/10 and 70/30 Cu-Ni alloys**. ERCuNi showcases **excellent mechanical properties**, **high resistance to corrosion, erosion, and biofouling**, and retains its strength and ductility even in marine and high-pressure settings.
