ER5183 Welding Wire
COREWELD 5183 is an ER5183 welding wire manufactured by Metracore Alloys. It is designed as an aluminum-magnesium filler metal for fusion welding compatible with 5xxx series aluminum alloys. Magnesium is the primary alloying element. It gives the deposited weld metal the strength and corrosion resistance required for marine, transportation, and structural fabrication work, particularly where joints resist sustained exposure to seawater or industrial atmospheres.
Wire classification follows AWS A5.10 / ASME SFA-5.10, and filler metal selection depends on the base alloy, service environment, and welding procedure. COREWELD 5183 supports MIG (GMAW) and TIG (GTAW) processes, as per the product form selected.
COREWELD 5183 Product Datasheet
The COREWELD 5183 ER5183 welding wire datasheet lists the full chemical composition, mechanical property values, available diameters, and packaging options for this product. Reviewing it before purchase confirms the exact specification match for a given welding procedure.
Understanding ER5183 Welding Wire
A nominal magnesium content of 4.3-5.2% places ER5183 welding wire, classified under AWS A5.10, among the highest-magnesium fillers in the common 5xxx series. This composition raises weld metal strength. It also helps maintain resistance to stress corrosion cracking in marine and industrial service, where sustained exposure to moisture and salts may accelerate degradation along grain boundaries in lower-magnesium deposits. The wire welds compatible aluminium-magnesium base alloys, most commonly 5083, 5086, 5154, 5254, and 5456. Marine fabrication, transportation structures, and structural fabrication work all benefit from the added strength and corrosion resistance. Selection depends on the base alloy, the service environment, the welding procedure qualified for the joint, and any applicable code requirement.

Chemical Composition and Mechanical Properties of ER5183
Chemical composition determines the weld deposit’s strength, ductility and corrosion behaviour, while mechanical properties determine how the welded joint performs under load. The values below apply to ER5183 welding wire and should be read alongside the base alloy’s own certified composition before procedure qualification.
Chemical Composition of ER5183
| Element | Composition (%) |
| Magnesium (Mg) | 4.3 – 5.2 |
| Manganese (Mn) | 0.50 – 1.0 |
| Chromium (Cr) | 0.05 – 0.25 |
| Silicon (Si) | 0.40 max |
| Iron (Fe) | 0.40 max |
| Copper (Cu) | 0.10 max |
| Zinc (Zn) | 0.25 max |
| Aluminium (Al) | Remainder |
These limits follow AWS A5.10 for the ER5183 classification. Published figures are specification limits, not a guaranteed COREWELD 5183 product composition; refer to the mill certificate issued with each batch.
Mechanical Properties of ER5183 Weld Metal
| Property | Value |
| Tensile Strength | 270 – 290 MPa (39,000 – 42,000 psi) |
| Yield Strength | 125 – 165 MPa (18,000 – 24,000 psi) |
| Elongation | 16 – 25% |
| Hardness | Approximately 45 HB (Brinell), as welded |
These are typical as-welded, all-weld-metal values recorded under controlled test conditions. Actual results on a production joint depend on the base alloy, welding procedure, joint design, and test method used, and should never be treated as a guaranteed property of every completed weld.
ER5183 MIG Wire vs. ER5183 TIG Rod
ER5183 MIG wire and ER5183 TIG rod share the same AWS A5.10 classification, but the product form and feeding method differ substantially. MIG wire is supplied on a spool and fed continuously through the welding gun by a wire feed unit, supporting higher deposition rates on long production welds. TIG rod, by contrast, comes in straight-cut lengths and is manually fed into the weld pool by the welder, one short addition at a time. Equipment requirements follow the same split: GMAW (MIG) requires a wire feeder and constant-voltage power source, while GTAW (TIG) needs a tungsten electrode, a separate filler rod, and typically a constant-current power source. MIG suits high-volume fabrication shop work. TIG suits precision joints, root passes, and thinner sections where heat input control matters more than speed.
ER5183 MIG Wire Applications
- Shipbuilding and marine hull fabrication
- Cryogenic and LNG storage tank welding
- Offshore and oil rig structural components
- Railcar and transportation equipment fabrication
- Bicycle frame and lightweight structural welding
- Pressure vessel fabrication in 5xxx series alloys
- General aluminium structural fabrication requiring higher weld strength
Manufacturing Process of ER5183 MIG Wire
- Material Selection: Aluminium-magnesium master alloy and high-purity aluminium billet stock are selected to meet the AWS A5.10 composition range for ER5183.
- Alloying & Melting: The billet is melted and alloyed to ensure that the magnesium, manganese and chromium content falls within specification before casting.
- Forming Processes: Cast billet is extruded and is drawn through a series of dies to the desired wire diameter.
- Composite Filler Metal Production: Drawn wire is cleaned, surface-finished, spooled or cut to length and packaged under controlled conditions to limit oxide pickup and contamination.
Key Benefits of COREWELD 5183 Filler Metal
COREWELD 5183 filler metal offers four key benefits for aluminium fabricators:
- Higher deposited weld strength, strong resistance to stress corrosion cracking, excellent colour match after anodising, and reliable feedability in semi-automatic welding.
- The elevated magnesium content raises the deposited weld metal’s strength beyond what lower-magnesium fillers such as ER4043 or ER5356 achieve on compatible base alloys.
- Resist stress corrosion cracking in marine atmospheres, a property that matters for hull plating, deck structures and offshore components exposed to salt spray.
- Relevant when supported by the applicable welding specification and manufacturer documentation for the joint in question.
- COREWELD 5183 feeds consistently through semi-automatic equipment, reducing arc interruptions on long production runs.
