Aluminium MIG wire containing nominal 5.3% Magnesium and 0.8% Manganese to produce a higher strength weld metal than the standard 5% Mg alloy. All elements are closely controlled for optimum weld strength. Produces a higher strength weld metal than standard 5% Mg 5356 alloy. It is designed to weld the widely used structural alloy 5083 when full matching strength is required.
