About ER CuNi

ERCuNi is a copper-nickel welding filler metal (wire/rod) for joining copper-nickel alloys, known for its excellent seawater corrosion resistance, used in shipbuilding, desalination, and marine industries, often for 70/30, 80/20, and 90/10 compositions, available in TIG/MIG forms.

Key Characteristics:

Composition: Primarily Copper (Cu) and Nickel (Ni) in various ratios (e.g., 70% Cu, 30% Ni).
Corrosion Resistance: Outstanding resistance to corrosion in saltwater environments.
Applications: Welding Cu-Ni alloys, cladding, surfacing steel (with a nickel barrier layer), marine, oil & gas, and desalination plants.
Welding Processes: Used for MIG (Gas Metal Arc Welding) and TIG (Gas Tungsten Arc Welding).
Properties: Provides high-quality, strong welds with good thermal and electrical conductivity.

Common Uses:

Shipbuilding and marine structures.
Desalination plants.
Oil refineries and chemical processing.
Welding dissimilar metals, like Cu-Ni to Monel alloys or Nickel 200.

How it's Used:

Typically applied with DCEN (Direct Current Electrode Negative) for TIG and DCEP (Direct Current Electrode Positive) for MIG.
Requires Argon or Argon/Helium shielding gas.
Preheating is generally not needed, but a short arc is recommended to prevent porosity.

In essence, ERCuNi is the go-to filler for tough, corrosion-prone environments, especially those involving saltwater, thanks to its robust copper-nickel alloy composition.
