Specification of 5754 H111 Aluminum Plate

Specific parameters

Alloy	5754	AlMg3
Temper	O, H111, H22, H24, H26, H32, H34	H111/H22/H24/H26 are the standard marine Temper
Thickness	3.0 – 500.0 mm	Medium and heavy aluminum plates can be produced
Width	600 – 3,000 mm	extra-wide aluminum plate
Length	16,000 mm	building large ship hull components

Mechanical properties

	O / H111	H22 / H24	H26
Tensile strength	190 – 240 MPa	240 – 280 MPa	265 – 305 MPa
Yield strength	≥ 80 – 100 MPa	≥ 160 – 185 MPa	≥ 190 – 245 MPa
elongation	12% – 25%	6% – 15%	4% – 10%
Typical hardness	45 – 55 HB	70 HB	78 HB

Noted: The H22/H24 temper offers high strength and retains good bending performance, making it the most widely used temper in ship structures; the O/H111 temper is flexible and has high elongation, making it suitable for deep-drawn components.

Chemical Composition

Element	Si	Fe	Cu	Mn	Mg	Cr	Zn	Ti	Al
Wt%	≤ 0.40	≤ 0.40	≤ 0.10	≤ 0.50	2.6 – 3.6	≤ 0.30	≤ 0.20	≤ 0.15	Balance

Key feature: The magnesium (Mg) content of 2.6–3.6% provides excellent resistance to seawater corrosion.

Uses of 5754 Marine Grade Aluminum Plate

5754 marine aluminum plate is widely used in various ship types and components. Key applications include:

Hull structure – shell plates, bottom plates, side plates (high strength & corrosion resistance)
Ship deck – covering and decoration (lightweight improves stability and fuel efficiency)
Internal structure – partitions, bulkheads, cabin ceilings (lightweight, strong, durable)
Deck equipment – portholes, hatches, boarding doors, gangways (corrosion-resistant & strong)
High-speed boats & yachts – ideal for weight-sensitive, high-performance vessels
