Abstract (en)

[origin: EP0967294A1] The dross forming tendency of an aluminum-magnesium alloy melt is reduced by addition of vanadium and a very small quantity of beryllium. The susceptibility of an aluminum alloy melt containing 2.5 wt.% Mg to dross formation is reduced by addition of 0.02-0.15 wt.% V and less than 60 ppm Be.
