When it comes to aluminum alloys, 5454 aluminium plate stands out for its unique combination of strength, corrosion resistance, and formability. Whether you’re involved in marine engineering, automotive manufacturing, or construction, understanding its alloy composition, mechanical properties, and applications is key to leveraging its benefits effectively. Let’s dive into the details.

Alloy Composition of 5454 Aluminium Plate

5454 is part of the 5xxx series of aluminum alloys, which are known for their high magnesium content— a feature that gives them excellent corrosion resistance, especially in marine environments. The typical composition of 5454 aluminium plate includes:

Alloy	Si	Fe	Cu	Mn	Mg	Zn	Cr	Ti	Others	Al
5454	0.25	0.4	0.1	0.5-1.0	2.4-3.0	0.25	0.05-0.2	0.2	0.2	Remain

Mechanical Properties of 5454 Aluminium Plate

The mechanical properties of 5454 aluminium plate are what make it a preferred choice in industries requiring both durability and formability. Here are its key mechanical characteristics (values are typical for the H32 temper, a common condition for 5454):

Alloy	Temper	Thickness (mm)	Tensile Strength (Rm/MPa)	Yield Strength (Rp0.2/MPa)	Elongation (≥, %)
5454	O/H111	0.2 - 0.5	215 - 275	85	12
		0.5 - 1.5			13
		1.5 - 3.0			15
		3.0 - 6.0			17
		6.0 - 12.5			18
		12.5 - 80	-	-
5454	H12	0.2 - 0.5	250 - 305	190	3
		0.5 - 1.5			4
		1.5 - 3.0			5
		3.0 - 6.0			6
5454	H22/H32	0.2 - 0.5	250 - 305	180	5
		0.5 - 1.5			6
		1.5 - 3.0			7
		3.0 - 6.0			8
5454	H14	0.2 - 0.5	270 - 325	220	2
		0.5 - 1.5			3
		1.5 - 3.0			3
		3.0 - 6.0			4
5454	H24/H34	0.2 - 0.5	270 - 325	200	4
		0.5 - 1.5			5
		1.5 - 3.0			6
		3.0 - 6.0			7
5454	H26/H36	0.2 - 1.5	290 - 345	230	3
		1.5 - 3.0			4
		3.0 - 6.0			5

Notably, 5454 aluminium plate can be heat-treated to different tempers (such as H111, H34, or H116) to adjust its mechanical properties, tailoring it to specific needs. For example, the H116 temper offers enhanced corrosion resistance, making it ideal for marine use.

Applications of 5454 Aluminium Plate

Thanks to its well-rounded properties, 5454 aluminium plate finds use in a variety of industries:

1. Automotive Gaskets

Ideal for sealing engine components, fluid reservoirs, and transmission housings, 5454 offers:

Tight conformity to irregular surfaces for leak-free seals, even under vibration.

Resistance to oils, coolants, and road salts, preventing degradation.

Stability across engine bay temperature ranges (cold starts to high heat).

Lightweight design to support fuel efficiency.

2. Automotive Heat Shields

Protects wiring, hoses, and plastic parts from engine/exhaust heat with:

Natural heat reflectivity to reduce radiant heat transfer.

Easy forming into complex shapes for tight engine bay fits.

Structural integrity at up to 300°C (short bursts).

Resistance to moisture, oil, and debris for long-term durability.

3. Oil Tank Bodies

Suitable for vehicle, machinery, and storage tanks thanks to:

Resistance to petroleum oils, hydraulic fluids, and additives.

Weldability (TIG/MIG) for seamless, pressure-resistant structures.

Strong yet lightweight build (handles 50-100 psi) to reduce load.

Versatile forming for sizes from small oil pans to large storage units.

4. Oil Tank Heads

Critical for sealing tank ends with:

Tensile strength (260-310 MPa) to withstand internal pressure.

Cold-formability into domed/elliptical/flat shapes without cracking.

Resistance to condensation, oil residue, and moisture.

Seamless welding compatibility with 5454 tank bodies.

5. Oil Baffles

Controls oil flow in engines/transmissions with:

Precision forming for tight fits in engine blocks and oil pans.

Abrasion resistance against moving parts and oil flow.

Immunity to oil, sludge, and coolant contamination.

Minimal weight to avoid impacting engine balance.

Why 5454 Aluminium Plate Stands Out

Its combination of corrosion resistance, formability, strength, and light weight makes it a cost-effective choice for these components. Whether in vehicles or industrial equipment, 5454 ensures reliable performance in harsh environments, from passenger cars to heavy machinery.
