ALUMINIUM WELDING CONSUMABLE · CLASSIFICATION-CONTROLLED SOURCING
ER5356 Aluminium Welding Wire
Technical sourcing of ER5356 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 5356 lists AWS A5.10 ER5356 and EN ISO 18273 S Al 5356 (AlMg5Cr(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.

Application Context
ER5356 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. ESAB warns of stress-corrosion cracking susceptibility when 5xxx base alloys are welded with OK Autrod 5356, the weld-pool Mg content is >3 %, and service temperature is >65 °C. This conditional warning is not a complete temperature rating or approval for other conditions. ESAB product description (undated). Source checked: 19 October 2026.

Availability, manufacturing location, current approvals, batch certificate and suitability must be confirmed for the exact order and approved WPS. The broader catalogue is supplementary, not proof of every classification or supply combination. Manufacturer references do not imply a commercial partnership.
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.
