5083 / ER5183 Aluminum Welding Wire

They’re the same alloy family. ER5183 is the AWS A5.10 classification for filler wire with chemistry tuned slightly above 5083 base metal — higher Mg (4.7–5.2 %) compensates for burn-off in the arc. When buyers say ‘5083 welding wire’, ER5183 is the product they need.

Yes. ER5356 is the general-purpose 5xxx filler and works well, giving roughly 10 % lower joint strength but excellent feedability and a nicer anodising colour match. For high-strength structural hull and tank welds, ER5183 is the specified choice.

ER4043’s low magnesium produces a joint with poor ductility and reduced corrosion resistance in high-Mg 5083 welds. It’s fine on 6xxx castings and extrusions, but structural 5083 work should always use 5xxx fillers — ER5183, ER5356 or ER5556.

MIG wire: 0.8, 0.9, 1.0, 1.2 and 1.6 mm on 1/2/7 kg plastic spools, 16–20 kg steel spools (D300) or 300 kg drums. TIG rods: 1.6–5.0 mm in 915/1,000 mm lengths. Cold-heading stock: 6–12 mm straightened wire.

All of them — D100/D200 plastic spools fit portable feeder spool guns; D300 steel spools and 300 kg drums fit shop floor feeders and robotic cells. Tell us your feeder model when ordering and we match the hub size.

No — ER5183 deposits match 5083 base-metal corrosion performance, with copper kept below 0.05 % so no galvanic cells form. This corrosion match is exactly why class societies approve it for hull plating welds.

The as-welded deposit delivers about 285 MPa tensile — roughly 90 % joint efficiency on 5083, matching what structural codes assume. The heat-affected zone of the base plate anneals to O-temper class; design weldments with code efficiency factors.

Yes — wire can be produced and certified under ABS, DNV, LR, BV and CCS filler approval schemes. Add the society requirement to your RFQ and we include the approval certificate with each lot.

Sealed vacuum-foil spools last 24+ months in dry storage. Once opened, use within about 12 months — longer exposure oxidises the surface and causes feed problems and porosity. Reseal partial spools in airtight bags.

Ninety percent of porosity is contamination: degrease with acetone, brush with a clean stainless brush, weld within hours of prep, and keep shielding gas dry and at correct flow. Hydrogen from moisture and oxide is the enemy — see our welding guide for the full technique.

Yes — 5083 straightened wire in 6, 8, 10 and 12 mm (custom diameters on request) for marine rivets, fasteners and cold-headed parts, in O/H12 temper for formability. It’s the corrosion-matched choice for fasteners in 5083 structure.

MOQ 500 kg; mixed diameters and spool sizes are fine within one order. Lead time is 10–20 days for running diameters, plus 25–35 days sea freight. Drum orders and class-approved lots run toward the longer end.

A 7 kg spool contains roughly 650 m of 1.2 mm wire. At typical 1.2 mm spray-transfer deposition rates that’s several hours of arc time — enough for a full shift on panel work. Weight per spool by diameter: order our wire weight table with your quote.

Yes — mixed-spool containers are routine for our export desk, per-line labelled with diameter, lot and certificate. Consolidating wire with your 5083 plate, tube or coil order cuts freight per kilo.

No — high magnesium drastically lowers conductivity. For electrical use, see our 1350/1050/1060 electrical-grade wire and busbar pages; 5083/5183 is strictly a mechanical and welding product.

Vacuum-foil sealed spools with desiccant inside, cartons on ISPM-15 pallets, shrink-wrapped container loads. Drums are steel-strapped with sealed pay-off openings. Wire should feed dry straight from the pack on arrival.
