Continuous solid wire suitable for welding of aluminium alloys with more than 3 % Mg, e.g. AlMg4.5Mn, AlMg5Mn and AlMg5Cr, where high tensile strength is required. Can also be used for materials of type AlMgSiCu and AlSi1MgMn and weldable AlZnMg-alloys, like AlZn4.5Mg1. The welding wire has small additions of Zr which increases the fine grained structure of weld deposit and makes it less sensitive to hot cracking during welding.
