Description

Application

Consumables suitable for welding aluminum and magnesium alloys with high mechanical properties. It has good corrosion-resistance (very good in marine atmosphere) and excellent color match after anodizing. Aluminum 5356 has excellent corrosion resistance properties, making it ideal for applications that require exposure to the elements, such as marine environments and chemical processing. The alloy’s corrosion resistance also makes it suitable for food processing and medical equipment use. Aluminum 5356 can withstand temperatures up to 500°F (260°C) without significant degradation or loss of strength. This makes it an excellent choice for applications that require exposure to high temperatures, such as aerospace components or automotive parts. Also Aluminum 5754 has excellent corrosion resistance especially to seawater and industrially polluted atmospheres. with higher strength than 5251. This high strength makes 5754 highly suited to flooring applications. Typically used for treadplate, shipbuilding, vehicle bodies, rivets, fishing industry equipment, food processing, welded chemical and nuclear structures.

Alloy Type

Magnesium alloyed aluminum for welding of alloys with a maximum of 5,0% Mg.

Microstructure

Face-centered cubic lattice.

Welding & PWHT

The weld surface commonly exhibits oxide residues and weld dirt, appearing gray to black, primarily composed of aluminum oxide and magnesium oxide. To prevent lack of fusion defects, it is advisable to eliminate these oxides before depositing another weld pass. A wire brush, whether manual or power-driven, proves to be the most effective tool for smut and oxide removal. It's crucial that the wire brush is clean and exclusively used for aluminum to avoid contamination. The gas metal arc welding process, characterized by a high melting and solidification rate of the weld metal, can lead to the entrapment of hydrogen gas in the welds. Understanding and controlling this aspect is vital for achieving satisfactory results. In the case of thicker plate materials, preheating to 150°C is necessary to manage the welding process effectively.
