What Is 5754 Aluminum?
5754 is a medium-strength Al-Mg non-heat-treatable alloy with 2.6–3.6% magnesium, supplemented by controlled additions of manganese (≤0.50%) and chromium (≤0.30%). It is strengthened exclusively through cold working (strain hardening).
5754 occupies the sweet spot between 5052 and 5083 — stronger and more corrosion-resistant than 5052, yet more formable and cost-effective than 5083. This balance has made it the preferred alloy for European automotive body panels and a strong performer in marine, chemical, and transport applications.

FAQ
What is 5754 aluminum used for?
5754 is most widely used for automotive body panels (doors, hoods, fenders in O temper), fuel tanks (H111/O per EN 14286), marine structures (H112 plate, DNV/ABS certified), and chemical/food tanks. Its combination of deep-drawing formability and corrosion resistance makes it the preferred Al-Mg alloy in European automotive manufacturing.
5754 vs. 5052 — which should I choose?
5754 offers ~5–10% higher strength and better seawater corrosion resistance than 5052, with comparable formability. Choose 5754 for automotive panels, marine applications, or wherever the slight strength premium justifies the cost. Choose 5052 for general-purpose sheet metal where cost is the primary driver.
5754 vs. 5083 — what is the difference?
5083 is ~25–30% stronger (H116: ≥303 MPa vs. 5754-H32: 220–270 MPa) and is the standard for classified marine hull plate (ASTM B928). 5754 is significantly more formable — making it better for complex shapes, automotive stamping, and non-structural marine parts. For structural hull plating requiring class certification, use 5083.
Can 5754 be welded?
Yes — excellent weldability with TIG, MIG, and resistance welding using ER5356 or ER5554 filler wire. Weld-zone strength equals approximately O-temper parent metal (~190 MPa tensile). 5754 has lower hot-cracking sensitivity than higher-Mg alloys like 5083.
What temper is best for deep drawing?
5754-O (fully annealed) with elongation ≥16%. It is the standard temper for automotive stamping operations including doors, hoods, and structural reinforcements.
Is 5754 suitable for marine use?
Yes — H112 plate is certified by DNV, ABS, BV, LR, and KR for marine structures. For general marine environments (superstructure panels, interiors, tanks), 5754 performs well. For primary hull plating on classified vessels, 5083-H116 is typically specified.
