ISO 24373:2018 — Copper and Copper-Alloy Welding Wires and Rods
Procurement reference for classification of solid wires and rods used for fusion welding of copper and copper alloys.
This MNK-G.S.A page is an original procurement summary. It does not reproduce or replace the protected ISO publication.
Scope in Procurement
- ISO 24373:2018 specifies classification requirements for solid wires and rods used for fusion welding of copper and copper alloys.
- Classification is based on chemical composition. The complete designation and manufacturer documentation must be verified instead of treating a shortened commercial name as sufficient evidence.
- The classification does not establish automatic suitability for a specific CuNi system, base material, seawater duty or repair. The approved WPS and project requirements govern selection.
Where This Standard Fits
| Product forms | Solid wires and rods |
| Material context | Fusion welding of copper and copper alloys |
| Classification basis | Chemical composition |
| Scope boundary | Does not approve a consumable for every CuNi or marine system |
Ordering and Document Controls
- Exact ISO classification and edition
- Wire or rod, diameter, package form and quantity
- Batch certificate, manufacturer datasheet and traceability
- Base alloy, joint and corrosion or seawater service
- Approved WPS, class, OEM and project requirements
- Destination and delivery schedule
Edition control: the purchase order, approved specification, manufacturer documentation and current authorised ISO publication govern the supply. A classification or material name alone does not prove compliance or application approval.
