5154A - AlMg3.5A Aluminium Plates, Sheets, Blocks(DIN, WNr)

Product Description

5154A (AlMg3.5A) is a high-grade aluminum-magnesium alloy that sits between the standard 5754 and the high-strength 5083. The "A" suffix in the European designation indicates a specific variation of the chemical composition aimed at optimizing weldability and ductility.

It is frequently specified for components that require a higher strength profile than AlMg3 but still need to maintain excellent formability.

Equivalent Designations

• DIN/WNr: AlMg3.5A / 3.3536

• EN: EN AW-5154A

• ISO: AlMg3.5

• Old British Standard: N5

Comparison: 5154A vs. 5754 and 5454

While they all share the "AlMg" family tree, 5154A has a higher Magnesium content ($3.1% - 3.8%$), which shifts its performance:

• Strength: It is stronger than 5754 (AlMg3) due to the extra 0.5% Magnesium.

• Ductility: It offers better elongation properties than 5454, making it superior for complex cold-forming.

• Corrosion: Like its siblings, it is exceptionally resistant to seawater and atmospheric corrosion.

Chemical Composition (Weight %)

The balance of Magnesium and Manganese is critical for the "A" variants stability:

• Magnesium (Mg): 3.1% 3.8%

• Manganese (Mn): Max 0.50%

• Chromium (Cr): Max 0.20%

• Iron (Fe): Max 0.50%

• Silicon (Si): Max 0.50%

• Aluminum (Al): Remainder

Industrial Applications

• Pressure Vessels: Used heavily in the construction of storage tanks and boilers.

• Cryogenic Equipment: Maintains its toughness at extremely low temperatures.

• Welded Tubes: Often used for manufacturing high-quality welded aluminum piping.

• Automotive/Transport: Structural parts for heavy-duty trailers and tankers.

• Wire Production: 5154A is a preferred alloy for manufacturing aluminum rivets and welding wires.

Available Forms

1. Sheets: Common in 1.0mm to 5mm thickness for paneling and tank walls.

2. Plates: Available in thicknesses up to 150mm for structural machining.

3. Blocks: Often used as "mold blocks" for plastic injection or vacuum forming where medium strength and high thermal conductivity are required.

Pro Tip: If you are welding 5154A, use 5183 or 5356 filler wire. These magnesium-matched fillers ensure the weld zone doesn't become the "weak link" in terms of corrosion resistance.

Excellent Corrosion and Heat Resistance

Manufactured with 3.1-3.9% magnesium, 5154A - AlMg3.5A aluminium alloys deliver outstanding corrosion resistance, especially in marine and industrial environments. They maintain structural integrity and mechanical properties up to 200C, ensuring dependable long-term performance in challenging conditions.


Versatile Applications and Superior Properties

With high weldability, good machinability, and a balance of strength and ductility, 5154A - AlMg3.5A products are favored for fabrication in transportation, construction, pressure vessels, and marine industries. Their non-magnetic nature, recyclable composition, and smooth mill finish further enhance their suitability for a wide range of engineering and industrial projects.
