5454 - AlMg3Mn Aluminium Plates, Sheets, Blocks(DIN, WNr)

Product Description

While similar to the 5754 alloy discussed previously, 5454 (AlMg3Mn) is specifically engineered for high-temperature service. It is often referred to as the "high-temperature version" of the 5000-series alloys because it is resistant to stress corrosion cracking when exposed to temperatures in the Density

Comparison: 5754 vs. 5454

While both are "AlMg3" types, the addition of Manganese (Mn) in 5454 provides distinct advantages:

• Temperature Stability: 5454 is the standard for applications that get hot. 5754 is excellent for room-temperature marine use but can become susceptible to corrosion if kept at high temperatures for long periods.

• Strength: 5454 typically offers slightly higher fatigue strength than 5754.

• Weldability: Both are excellent, but 5454 is specifically designed to maintain its structural integrity and corrosion resistance after welding in heavy-duty environments.

Chemical Composition (Weight %)

The Manganese content is the "secret sauce" that stabilizes the alloy against heat.

• Magnesium (Mg): 2.4% 3.0%

• Manganese (Mn): 0.5% 1.0%

• Chromium (Cr): 0.05% 0.20%

• Copper (Cu): Max 0.10%

• Aluminum (Al): Remainder

Applications for Plates & Blocks

Because 5454 can handle heat and chemicals simultaneously, you will find it in:

• Road Tankers: Used for transporting hot substances (like liquid bitumen or chemicals).

• Pressure Vessels: Specifically those operating at elevated temperatures.

• Automotive: Wheels and structural components that may be near engine heat.

• Marine: Large structural plates for high-speed craft where friction heat or engine room temperatures are factors.

Available Forms

• Sheets: Usually available in thicknesses from 0.5mm to 6mm.

• Plates: Heavy plates for structural builds (6mm up to 200mm+).

• Blocks: Often custom-cut from thick rolled plate for tool making or heat-resistant mold bases.

Technical Tip: If you are choosing between these two for a marine environment that stays cool, 5754 is your cost-effective standard. If your application involves "hot" cycles (above $65{circ}C$), you should specify 5454 to avoid long-term material degradation.

Outstanding Corrosion and Heat Resistance

5454 aluminium alloy is distinguished by its exceptional resistance to seawater, industrial atmospheres, and even low temperatures, making it a dependable choice for marine and chemical applications. Additionally, it maintains good mechanical properties up to 65C and is suitable for cryogenic conditions, ensuring flexibility across a range of demanding environments.


Versatile Formability and Fabrication

This alloy offers excellent weldability and good machinability, allowing for easy fabrication in various plate, sheet, and block forms. Its superb elongation (12-20%) and moderate tensile strength make it perfect for structural and pressure vessel projects where forming, joining, and adapting material is critical to success.


Custom Sizes and Reliable Performance

Available in thicknesses from 6 mm to 250 mm and customizable dimensions, 5454 aluminium plates, sheets, and blocks meet diverse industry needs. Consistent quality standards, mill finish surfaces, and standard export packaging ensure that products arrive in optimal condition for immediate use or further processing.
