Aluminum–magnesium · 5xxx series
5754 Aluminum Alloy
5754 contains 2.6–3.6% magnesium and is the grade European automotive and rail suppliers specify where 5052 is not quite strong enough and 5083 is too stiff to form. It forms and welds well, and it is normally ordered to EN 485 rather than ASTM.

Chemistry
5754 Chemical Composition Limits
Percent by weight. These are the registered limits, not a typical analysis — a heat that sits anywhere inside them is still 5754.
| Element | Limit (% wt) | Element | Limit (% wt) |
|---|---|---|---|
| Si | 0.40 max | Fe | 0.40 max |
| Cu | 0.10 max | Mn | 0.50 max |
| Mg | 2.6 – 3.6 | Cr | 0.30 max |
| Zn | 0.20 max | Ti | 0.15 max |
| Mn + Cr | 0.10 – 0.60 | Other, each | 0.05 max |
| Other, total | 0.15 max | Al | Remainder |
Composition limits are the Aluminum Association registered ranges, which is what ASTM B209 and EN 573-3 both refer back to. Mechanical values are typical for the temper shown, not acceptance minima — the minima are set by the product standard, and the mill certificate reports the measured values for your heat.

Typical Mechanical Properties by Temper
Room temperature, longitudinal direction. Use these to compare grades and tempers — the acceptance figures for your order come from the product standard and are reported on the mill certificate for the actual heat.
| Temper | Tensile (MPa) | Yield (MPa) | Elongation (%) | Thermal conductivity (W/m·K) |
|---|---|---|---|---|
| O | 210 | 90 | 19 | 130 |
Other tempers in the 5754 range — O · H111 · H22 · H24 · H32 · H34 — are available to order. Values for those are quoted with the offer rather than assumed from this table.
Forms
5754 in the Forms We Supply
The same alloy behaves differently as coil, plate and extrusion because the rolling or extrusion route sets the temper and the surface. Pick the form first, then the temper.
Aluminum Sheet & Plate
Rolled flat product from 0.2 mm foil stock to 200 mm plate.
0.2 – 200 mm · 600 – 2,200 mm
Aluminum Coil
Continuously cast or hot-rolled coil for roll forming and stamping.
0.2 – 8.0 mm · 600 – 2,200 mm
Aluminum Strip
Slit coil with controlled edge burr and camber.
0.1 – 3.0 mm · 10 – 1,600 mm
Where it is used
Typical End Uses for 5754
Transport & Automotive
Weight reduction per body panel is the entire business case. Formability and weldability decide the grade.
Industrial & Machining
Machining stock. Grain direction, residual stress relief (T651) and dimensional stability decide whether the part moves after it is cut.
Marine & Shipbuilding
Mg-alloyed plate resists seawater and welds without losing strength. This is the series classification societies expect to see on hull plate.
Selection
Choose 5754 When — and When Not To
Choose 5754 when
Body panels, rail interiors, silkscreen and anodizing stock, and welded structures where the drawing is written to EN 485.
Think again if
High-strength structural parts — the grade is work-hardened only. Above 65 °C service the usual 5xxx sensitization limit applies.
Before you ask
5754 — Questions Buyers Ask
5754 or 5052 for automotive panels?
5754 if the drawing is European; 5052 if it is North American. Mechanically they are close, but the composition limits differ and a certificate has to match the grade named on the drawing.
Why is 5754 popular for anodized trim?
It takes a uniform anodic film with less streaking than 5052, and the surface quality from European rolling lines is consistent enough for visible trim without special rolling.
Can 5754 be laser welded?
Yes, and it is one of the more forgiving 5xxx grades for laser and MIG processes. Filler is normally 5356. Because the alloy is not heat-treatable, the softened heat-affected zone sets the design strength.
