Aluminium MIG wire is used to weld aluminium. It is important to select a MIG wire of the same grade as the workpiece, or with the closest melting temperature. Our aluminium MIG welding wire is available in 1050, 4043, 4047, 5183, 5356, and 5556 grade in a choice of diameters. These products are sold by weight rather than length and are available as 0.5kg, 2kg, and 6.5kg reels.
