5454 Aluminum Sheet Description
The 5454 aluminum sheet is a non-heat-treatable Al-Mg alloy. It is highly valued for its excellent corrosion resistance, moderate-to-high strength, and reliable performance in elevated temperature environments. Compared to other alloys, it performs exceptionally well in industrial applications where heat and moisture are constant factors.
At GNEE, we manufacture and supply industrial-grade 5454 aluminum sheets. We focus on providing flexible customized sizes, strict tolerance control, and reliable quality for industries such as tank truck manufacturing, pressure vessel production, and marine engineering.
Key Features of 5454 Aluminum
When you buy 5454 aluminum sheets, you are paying for durability and structural safety. The core advantages include:
- Corrosion Resistance: Performs extremely well in marine environments and industrial chemical settings.
- High-Temperature Stability: Offers better strength and performance at elevated temperatures compared to 5052 aluminum.
- Weldability: Easy to weld using standard industrial methods with high joint strength.
- Formability: Good workability, especially in softer tempers, making it easy to bend and shape.
- Stress Cracking Resistance: Strong resistance to stress corrosion cracking, which is vital for transport tanks.
Chemical Composition of 5454 Aluminum
The chemical balance of 5454 aluminum gives it its unique marine and heat-resistant properties. Magnesium (Mg) is the primary alloying element.
| Element | Content (%) |
| Magnesium (Mg) | 2.4 – 3.0 |
| Manganese (Mn) | 0.5 – 1.0 |
| Iron (Fe) | ≤ 0.4 |
| Silicon (Si) | ≤ 0.25 |
| Zinc (Zn) | ≤ 0.25 |
| Chromium (Cr) | 0.05 – 0.20 |
| Copper (Cu) | ≤ 0.10 |
| Aluminum (Al) | Balance |
Mechanical Properties of 5454 Aluminum
Before placing an order, engineering teams need to verify the mechanical properties. Below are the typical values for 5454 aluminum plates.
| Property | Typical Value |
| Tensile Strength | 240 – 305 MPa |
| Yield Strength | ≥ 110 MPa |
| Elongation | ≥ 12% |
| Hardness | ~70 HB |
Physical Properties of Aluminum 5454
| Property | Typical Value |
| Density | 2.66–2.70 g/cm³ |
| Melting Point | 590–645 °C |
| Thermal Conductivity | 130–150 W/m·K |
| Thermal Expansion | 23.7–24 ×10⁻⁶ /K |
| Electrical Conductivity | 33–35% IACS |
Available Tempers of 5454 Aluminum Sheet
Choosing the right temper is the most critical step in your procurement process. It directly affects your fabrication process and final product safety. GNEE supplies 5454 aluminum in several tempers:
| Temper | Strength Level | Formability | Recommended Application |
| 5454 O (Annealed) | Low | Excellent | Tank heads, deep drawing parts, complex bending |
| 5454 H111 | Medium-low | Good | Structural parts requiring slight forming |
| 5454 H32 | Medium | Balanced | Tank bodies, general welded structures |
| 5454 H34 | Medium-high | Lower | High-strength flat structural components |
GNEE Procurement Advice:
For tank truck manufacturers, we highly recommend buying 5454 H32 temper for the main tank body because it offers the best balance of strength and price. However, for the tank heads (end caps), you must use 5454 O temper because the deep drawing process requires maximum formability to prevent cracking. Do not over-specify H34 unless your engineering drawing strictly requires it, as it will increase your processing difficulty and material cost.

Common Industry Applications of 5454 Aluminum Sheet
5454 aluminum is not for decorative use. It is a heavy-duty industrial metal. Common real-world applications include:
- Tank Truck Manufacturing
This is the largest market for 5454. It is widely used for fuel tanker bodies, chemical transport tanks, and LPG tank structures. Its light weight helps increase the vehicle's payload capacity, while its strength ensures safety during liquid transport.
- Pressure Vessels
Because 5454 maintains good mechanical properties in high-temperature environments, it is widely used to manufacture storage tanks and heat-resistant industrial containers that operate under pressure.
- Marine Engineering
Due to its high resistance to seawater corrosion, shipbuilders use 5454 aluminum sheets for ship deck structures, workboat hulls, and offshore platform components.
- General Heavy Industry
It is frequently used for heavy-duty welded structures, industrial flooring, and heavy machinery covers where 5052 aluminum is simply not strong enough.
Price Calculation Formula
The final price of a 5454 aluminum sheet from GNEE is calculated as:
Final Price = Aluminum Ingot Price (LME rate) + Processing Cost + Specification Premium
Key factors that will increase your cost:
- Thickness: Thicker plates require more material, increasing the total sheet cost.
- Temper: Processing H34 takes more effort than O temper, making it slightly more expensive.
- Tolerance: Standard tolerance is cost-effective. Requesting extremely tight thickness tolerances will increase the machining fee.
- Quantity: Bulk orders significantly reduce the processing cost per ton.
- Non-Standard Sizes: Custom sizes are welcome, but excessive scrap during cutting may affect the final unit price.
tolerances of 5454 aluminum sheet plate
| Thickness tolerances within the following width ranges | ||||
| Thickness | ≤1250 | >1250-1600 | >1600-2000 | >2000-2650 |
| 3.00-3.50 | +0.28 | +0.28 | +0.30 | +0.40 |
| >3.50-6.00 | +0.32 | +0.32 | +0.40 | +0.45 |
| >6.00-8.00 | +0.38 | +0.45 | +0.50 | +0.60 |
| >8.00-12.00 | +0.45 | +0.55 | +0.65 | +0.80 |
Quality Control
For industrial applications, the appearance is secondary to functionality, but surface defects can lead to weak points.
The standard supply is Mill Finish. Before packing, GNEE inspectors check for:
- No deep surface scratches that affect thickness.
- No heavy oil stains that will interfere with welding.
- No oxidation or water spots.
- Clean, crack-free edges (especially important for plates used in bending).
Packaging and Shipping
Poor packaging ruins good aluminum. Aluminum is sensitive to moisture during sea freight. GNEE uses standard seaworthy export packaging to ensure your goods arrive safely:
- Bottom layer: Strong wooden pallets.
- Inner layer: Moisture-proof plastic film and desiccant.
- Outer layer: Hardboard or kraft paper protection.
- Strapping: Steel or heavy-duty plastic straps.
- Optional: We can apply anti-scratch PE film to the sheet surface upon request.
