Other 5xxx grades we supply
Same marine family, different balance of strength, formability and service temperature.
Which temper do you need?
Pick the stabilised temper for the exposure and forming requirements of each part.
The workhorse temper for superstructures, tanks and general marine fabrication.
- 240 MPa tensile / 130 MPa proof min
- Good weldability
- Excellent formability
Hot-rolled plate temper for thicker sections and welded structures.
- Lower strength, high ductility
- Used in deck house sides
- Tanks and bulkheads
Strain-hardened sheet for panels and interior work.
- Higher strength than H111
- Good fatigue resistance
- Used in small craft superstructure
Where 5754 plate is used on board
5754 plate thickness starts at 3 mm; heavier sections carry primary loads.
Superstructure sides
5754-H111 plate forms deck house walls, bulkheads and bridge wings.
3–12 mmTanks & bunkers
Welded tanks for fuel, water and lube oil where strength requirements are moderate.
3–10 mmGeneral fabrication
Brackets, foundations and non-load-bearing structures across the vessel.
3–20 mmSmall craft hulls
Lower strength is acceptable for small boats and fishing craft.
3–8 mmWhy 5754 wins in marine service
Four numbers that decide the specification.
Same section modulus, lower center of gravity and fuel burn.
Compatible filler chemistry keeps joints corrosion-resistant without post-weld heat treatment.
Mill test certificate issued by the producing mill and countersigned by our QC team.
For long-term service above this, 5454 is the usual alternative.
Real-world corrosion resistance
8-year atmospheric and splash-zone exposure data on Al–Mg 5xxx alloys.
- Stabilised tempers: H116/H321 keep intergranular and exfoliation corrosion low in continuous immersion and splash zones.
- Lot-release testing: ASTM G66 ASSET and G67 NAMLT confirm resistance to sensitisation before shipment.
- Design matters: isolate aluminum from dissimilar metals, avoid standing water in crevices, and stay below the 65 °C long-term ceiling.
Actual rates depend on local water chemistry, design and maintenance.
5754 mechanical properties
Minimum / typical values per ASTM B209 / B928. Certified values are shown on the EN 10204 3.1 MTC supplied with each batch.
| Temper | Tensile Rm (MPa) | Proof Rp0.2 (MPa) | Elongation A50 (%) | Typical marine use |
|---|---|---|---|---|
| O | 190–250 | 60–100 | ≥18 | Deep drawing, complex forming |
| H111 | 240 min | ≥130 | ≥14 | Superstructures, tanks, bulkheads |
| H112 | 220–280 | ≥100 | ≥12 | Hot-rolled plate, welded structure |
| H32 | 260–330 | ≥160 | ≥8 | Panels, stiffeners |
5754 is chosen when ease of forming and welding outweighs the need for 5083-level strength.
5754 against the rest of the 5xxx family
Every grade below we supply. Choose on strength, forming and service temperature — not on habit.
| Alloy | Mg content (%) | Tensile Rm (MPa) | Proof Rp0.2 (MPa) | Marine corrosion | Best used for |
|---|---|---|---|---|---|
| 5083 | 4.0–4.9 | 305–385 | ≥215 | Excellent — G66/G67 | Hull, deck, LNG secondary barrier |
| 5086 | 3.5–4.5 | 275–345 | ≥195 | Excellent | Hull plating, fast craft, pressure vessels |
| 5754 | 2.6–3.6 | 215–275 | ≥130 | Very good | Superstructures, tanks, general fabrication |
| 5052 | 2.2–2.8 | 215–265 | ≥160 | Very good | Fuel tanks, panelling, ducting |
| 5454 | 2.4–3.0 | 240–290 | ≥180 | Excellent at temperature | Warm service above 65 °C, chemical carriers |
| 5182 | 4.0–5.0 | 275–350 | ≥130 | Good | Tank bodies, stiffeners, reinforcement |
Typical values for common marine tempers. Higher-magnesium grades give more strength but were designed for different forming limits — confirm the temper before substituting.

3.1 MTCFrequently asked questions
What is 5754 used for on ships?
Superstructures, deck houses, tanks, bulkheads and general fabricated parts where high formability is needed.
Which temper should I order?
H111 for most marine sheet and plate. H112 for hot-rolled thicker plate. H32/H34 for higher-strength panels.
Is 5754 as corrosion resistant as 5083?
Very good, but 5083 is preferred for continuous immersion and splash zones. 5754 is excellent for superstructure and tanks.
Can 5754 be welded?
Yes. ER5356 is the standard filler; strength loss in the heat-affected zone is normal and allowed for in design.
What thickness range can you supply?
Plate 3–50 mm, sheet 0.5–6 mm, coil slit to width.
Does 5754 meet marine classification?
Yes. DNV and other major societies approve 5754 for non-primary marine structures; certification is available on request.
What certificate comes with each batch?
EN 10204 3.1 MTC, issued by the producing mill and countersigned by our QC team.
Can you supply cut-to-size 5754 plate?
Yes — send dimensions or a nesting file for a quote.
