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

Product Description

5154 Aluminium (AlMg3.5) is a medium-to-high strength, non-heat-treatable alloy from the 5000 series (Aluminium-Magnesium family). It is specifically recognized for its excellent corrosion resistance, particularly in marine environments, and its superior weldability.

1. Key Designations and Equivalents

2. Chemical Composition (Typical %)

The "3.5" in AlMg3.5 refers to the nominal Magnesium content, which provides the alloy's strength and corrosion resistance.

• Magnesium (Mg): 3.10 “ 3.90%

• Manganese (Mn): 0.10 “ 0.50%

• Chromium (Cr): 0.15 “ 0.35%

• Iron (Fe): 0.40% max

• Silicon (Si): 0.25% max

• Aluminium (Al): Remainder

3. Mechanical Properties

Properties vary significantly based on the temper (e.g., O for annealed, H111 for work-hardened).

4. Physical Properties

• Density: 2.66 $g/cm3$

• Melting Range: 593C “ 643C

• Thermal Conductivity: 127 W/m·K

• Electrical Conductivity: 32% IACS

• Modulus of Elasticity: 69 GPa

5. Common Applications

Due to its resistance to saltwater and chemicals, 5154 is a "workhorse" for heavy-duty industrial fabrication:

• Marine Industry: Ship hulls, masts, and saltwater piping.

• Pressure Vessels: Unfired welded pressure vessels and storage tanks.

• Chemical Industry: Equipment for handling highly corrosive chemicals (e.g., hydrogen peroxide).

• Fasteners: Cold-headed rivets and wire mesh cloth.

• Transportation: Trailer tanks and automotive structural parts.

6. Fabrication Characteristics

• Weldability: Excellent. It can be welded using MIG and TIG methods with filler alloys like 5356 or 5554.

• Machinability: Poor to Fair. Like most high-magnesium alloys, it can be "gummy" during machining; best results are found in harder tempers.

• Corrosion Resistance: Excellent. Superior resistance to atmospheric and seawater corrosion compared to the 2000 or 7000 series.
