Weld Star ER 5356 Wire [7kg Spool]

The Weld Star ER 5356 (AlMg5) is a high quality aluminium solid MIG wire alloyed with 5% Magnesium. This is the most widely used aluminium welding wire for structural applications due to its high tensile strength and exceptional resistance to atmospheric and marine corrosion.

Designed for welding 5xxx series and 6xxx series aluminum alloys, the 5356 wire provides a "whiter" weld finish that is an excellent match for anodizing. Unlike the softer 4043 wire, 5356 is stiffer, which aids in significantly better wire feeding characteristics through longer MIG torches. Whether you are building boat hulls, automotive frames, or structural architectural components, Weld Star ER 5356 delivers the metallurgical integrity and feed ability required for professional aluminium fabrication.

Key Features

Marine Grade Performance: Exceptional resistance to saltwater corrosion, making it the primary choice for shipbuilding and offshore repairs.

High Shear Strength: Provides superior joint strength compared to 4043 alloys, essential for structural and load bearing assemblies.

Anodising Match: Produces a high quality colour match after anodising, ideal for architectural and decorative aluminium work.

Superior Feed ability: The 5% Magnesium content makes the wire stiffer than other aluminium alloys, reducing "bird nesting" and ensuring smoother feeding.

Broad Compatibility: Suitable for welding a wide range of base materials, including 5052, 5083, 5454, and 6061 alloys.

Precision Layer Wound: Supplied on 7kg spools, precision wound to ensure consistent arc stability and reduced downtime.
