Seawater and HF Duty Stock
We hold this Monel 400 welding wire for alkylation, marine and brine work where 300-series stainless pits or cracks.
Strength from Cold Work Alone
Specifically, this Monel 400 welding wire cannot be age hardened, so a heavier drawing pass rather than a heat treatment raises its yield.

Moreover, the mill certificate, hardness records and export papers for this Monel 400 welding wire reach you as one set.
PRODUCT OVERVIEW
About Monel 400 Welding Wire
Monel 400 welding wire covers the filler metals classified for joining UNS N04400 and N05500 base metal. The bare product runs as ERNiCu-7 per AWS A5.14, and the covered electrode runs as ENiCu-7 per AWS A5.11.
We supply Monel 400 welding wire as straight TIG rods, wound MIG spools and sealed electrode packs. Copper carried by the deposit matches the parent metal, so a joint made with this Monel 400 welding wire keeps the seawater and acid behaviour of the base metal.
Meanwhile, the base-metal chemistry behind this Monel 400 welding wire sits on our Monel 400 material page for weld procedure work.
PRODUCT FEATURES
Key Features of Monel 400 Welding Wire
Monel 400 welding wire arrives in UNS N04400, the solid-solution nickel-copper alloy that holds nickel at 63% and above. We provide ASTM B164 and ASME SB164 welding wire as ERNiCu-7 bare wire, TIG rods and MIG spools for marine yards, alkylation units and brine plant. Every Monel 400 welding wire order carries heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Monel 400
Matching Deposit
For example, an ERNiCu-7 deposit from this Monel 400 welding wire matches the corrosion behaviour of the parent nickel-copper alloy.
01
Copper-Nickel Corrosion Life
Specifically, joints made with this Monel 400 welding wire hold up in flowing seawater and reducing acids.
02
Two Grades Covered
Moreover, this Monel 400 welding wire serves both UNS N04400 and the age-hardenable UNS N05500.
03
Dissimilar Joining Range
In addition, this Monel 400 welding wire joins Monel to carbon steel, stainless steel and copper-nickel alloys.
04
Three Process Routes

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
UNS N04400 carries nickel as its balance and holds copper inside a 28.0% to 34.0% window, so every heat record for this welding wire prints a copper figure rather than a grade name. Besides, that window is what keeps the seawater and acid behaviour of this welding wire repeatable from heat to heat.
For the full element-by-element limit set, open the composition breakdown held on the Monel 400 material page for this welding wire.
Mechanical Properties
The all-weld-metal figures below summarize published ERNiCu-7 and ENiCu-7 classification data for Monel 400 welding wire. Note that AWS does not publish yield strength as a classified property for these fillers.
