ALUMINIUM WELDING CONSUMABLE · CLASSIFICATION-CONTROLLED SOURCING
ER5556A Aluminium Welding Wire
Technical sourcing of ER5556A aluminium welding wire and related supply forms by exact classification, diameter, package, approvals and batch documentation.
MNK-G.S.A coordinates supply for marine, industrial fabrication and repair requirements. Final consumable selection remains controlled by the approved WPS, base material, joint design, process, service conditions, class and OEM requirements.
Material and Classification Identity
- The manufacturer catalogue maps AWS A5.10 / SFA-5.10 classification ER5556A to EN ISO 18273 classification S Al 5556A (AlMg5Mn1(A)).
- AWS and EN ISO classifications are technical identifiers; they do not prove that every manufacturer, diameter, package or approval is available together.
- A matching commercial name does not authorize substitution. The customer specification and approved welding procedure remain controlling.
Standards and Supply Definition
| AWS classification framework | AWS A5.10/A5.10M:2023 for bare aluminium and aluminium-alloy electrodes and rods |
| International classification | ISO 18273:2015 — S Al 5556A (AlMg5Mn1(A)) |
| Supply form | MIG/GMAW solid wire; straight rod where produced and certified for the exact classification |
| Ordering definition | Classification, process, diameter, spool or rod package, batch, approvals and certificate requirements |
| Selection authority | Approved WPS/PQR, class, OEM and customer specification |
Application Context
ER5556A belongs to the aluminium-magnesium filler family. Application suitability cannot be determined from the filler designation alone. Base-alloy grade and temper, joint geometry, required strength, corrosion exposure, service temperature, anodising requirements and welding procedure must be reviewed before quotation.
RFQ and Quality Controls
- Exact AWS and/or EN ISO classification
- MIG wire or TIG rod form, diameter and package
- Manufacturing location and valid class or third-party approvals
- Batch certificate, chemical analysis and traceability
- Base material, WPS/PQR, service conditions and destination
