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, classification-society and OEM requirements.

Material and Classification Identity
- ESAB OK Autrod 5556A lists AWS A5.10 ER5556A and EN ISO 18273 S Al 5556A (AlMg5Mn).
- 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.

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 classification-society or third-party approvals
- Batch certificate, chemical analysis and traceability
- Base material, WPS/PQR, service conditions and destination

These references do not establish a supply partnership, stock availability or approval for a particular project. The AWS and ISO links identify standard publications; they do not certify the offered product. Approvals, manufacturing location, diameter, packaging and batch documents are checked for each quotation.
Relevant ISO Reference
Use the current authorised ISO publication together with the governing specification, manufacturer documentation and project requirements. A reference link alone does not establish grade equivalence, product compliance or application approval.
