5454 aluminum sheet is an Al-Mg-Mn alloy designed for applications that need a useful balance of corrosion resistance, weldability, strength, and formability. It is often considered for tanks, chemical equipment, heat-transfer components, and other fabricated structures where welded performance is important.

This page is a 5454 material data card. It focuses on composition, typical mechanical properties, welding considerations, sheet forms, applications, and the main material standard. It is different from a supplier-focused guide that discusses sourcing and availability.

5454 Aluminum Sheet: Composition at a Glance

5454 belongs to the 5xxx series of aluminum-magnesium alloys. Magnesium provides the main strengthening effect, while manganese contributes to strength and helps support the alloy's corrosion-performance profile.

Exact chemical limits should always be checked against the applicable product specification and purchase standard. Minor elements such as Fe, Si, Cu, and Zn are also controlled.

5454 Mechanical Properties: H32 Data Card

The H32 temper is commonly referenced when a balance of strength and formability is required. A representative tensile strength is around 250 MPa, although the actual value depends on product thickness and the applicable specification.

These values are intended as a quick reference rather than a replacement for the governing specification. For critical structures, the certificate and applicable standard should be used for final acceptance.

5454 Sheet: Welding and Welded Performance

One of the important reasons for selecting 5454 is its suitability for welded fabrication. The alloy can be used in fabricated tanks, containers, and equipment where multiple sheet sections must be joined.

As with other non-heat-treatable 5xxx alloys, welding changes the local temper and therefore the strength near the weld. The welded joint should not simply be assigned the parent-sheet H32 strength. Joint design, filler alloy, welding process, heat input, and plate or sheet thickness all affect the final result.

5454 and Stress-Corrosion Considerations

5454 is a lower-magnesium 5xxx alloy than grades such as 5083. This makes its behavior relevant when welded structures are exposed to corrosive environments and residual stress.

Its resistance to stress-corrosion-related problems is one reason 5454 can be considered for tank and transport applications. However, stress-corrosion resistance should not be treated as a simple universal ranking between alloys. Actual performance depends on alloy condition, temperature, environment, stress level, welding, and service conditions.

For a welded tank or chemical-service component, the material selection should therefore consider the complete service environment rather than composition alone.

5454 Aluminum Sheet Forms and Sizes

5454 can be supplied as sheet and plate in different thicknesses and dimensions. For fabricated tank and equipment applications, heavier gauges may be selected when greater stiffness or structural capacity is required.

Where Is 5454 Aluminum Sheet Used?

The alloy is particularly relevant to welded equipment and transport structures where corrosion resistance and fabrication performance are important.

• Tank-truck liners and tank components: suitable where corrosion resistance and welded fabrication are required.
• Chemical containers: considered for selected chemical-service equipment after compatibility review.
• Heat-exchange equipment: used where a combination of corrosion resistance, formability, and thermal conductivity is needed.
• Transport equipment: useful where low density and welded construction are important.
• Fabricated vessels and containers: selected for applications where the material specification permits its use.

5454 vs 5083: Quick Material Comparison

5454 and 5083 are both Al-Mg alloys, but they occupy different positions in engineering applications. 5083 provides a higher-strength option, while 5454 can be attractive when a combination of moderate strength, weldability, formability, and corrosion performance is preferred.

Neither alloy should be selected only from a grade comparison table. Tank design code, operating temperature, chemical medium, welding procedure, thickness, and required certification should be checked before material approval.

5454 Aluminum Standard: ASTM B209

ASTM B209 is a key specification for aluminium and aluminium-alloy sheet and plate. When 5454 sheet is ordered to this standard, the purchase specification should identify the alloy, temper, dimensions, and applicable product requirements.

For engineering projects, it is good practice to request the material certificate and confirm that the supplied product conforms to the specified edition and grade requirements. Additional project standards may also apply depending on the application.

5454 Aluminum Sheet Purchasing Checklist

• Specify 5454 as the alloy.
• Specify the required temper, such as H32.
• Confirm thickness, width, and length.
• State the applicable standard, such as ASTM B209.
• Identify whether the material will be welded.
• Provide the service medium and temperature for chemical or tank applications.
• Confirm surface and protection requirements.
• Request the applicable material certificate and inspection documentation.

Teda Ganghua 5454 Aluminium Sheet Supply

For buyers sourcing 5454 for tanks, chemical equipment, heat-transfer components, or other welded applications, Teda Ganghua can review the required alloy, temper, thickness, dimensions, standard, quantity, and application before quotation.

For a project that requires a specific 5454 sheet specification, buyers can review aluminium sheet products and provide the target grade, temper, size, standard, and quantity. A drawing or application description is useful when the sheet will be cut, formed, or welded into a finished component.

For tank and chemical-service projects, the final material selection should be matched to the applicable design code and operating environment. This helps ensure that the quoted material is suitable not only by grade, but also by temper, thickness, documentation, and fabrication requirements.

FAQs About 5454 Aluminum Sheet

What is 5454 aluminum sheet?

5454 is a non-heat-treatable Al-Mg-Mn alloy used where corrosion resistance, weldability, moderate strength, and formability are required. It is associated with tanks, transport equipment, chemical equipment, and heat-transfer applications.

What is the composition of 5454 aluminum?

A quick reference composition is Mg 2.4–3.0%, Mn 0.5–1.0%, and Cr up to 0.2%, with aluminium as the balance. Exact limits should be confirmed against the applicable product specification.

What is the tensile strength of 5454-H32?

A representative tensile-strength value for 5454-H32 is around 250 MPa. The exact required value depends on product thickness and the governing material specification.

Is 5454 aluminum good for welding?

Yes. 5454 is well suited to welded fabrication when the correct welding procedure, filler, joint design, and heat-input controls are used. The strength of the welded area should be evaluated separately from the parent H32 material.

What standard covers 5454 aluminum sheet?

ASTM B209 is a major specification for aluminium and aluminium-alloy sheet and plate and can cover 5454 products when the applicable alloy and temper requirements are specified.
