Abstract
In a process to reduce the susceptibility to dross-forming of an aluminium alloy melt with a content of at least 2.5 w. % magnesium, to the melt is added 0.02 to 0.15 w. % vanadium and less than 60 ppm beryllium. By the addition of vanadium, the beryllium addition can be reduced and at the same time the dross-forming resistance of the melt increased.
