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.

Abstract: An annealing basket made of steel, receiving mass-produced aluminium parts (20) for the degreasing and softening thereof, comprising a bottom and side by a frame. At least one side wall (16) is joined to the walls that protrude from said bottom and are defined frame (12) by means of at least one aluminium element (26) that can be plastically deformed when heated to an annealing temperature as a result of the pressure that is exerted on the side walls (16) and occurs in the annealing basket (10) due to thermal expansion of said aluminium parts (20), whereby the side wall (16) moves outwards to a certain degree under the effect of the increase in the volume of said basket in at least one area that is adjacent to the frame.

Abstract: A brake disc (10) has a cover (12) made of a cast aluminium alloy and a brake ring (14) made of cast steel or cast iron. The cover (12) is cast onto pockets (22) which have a radially inwardly facing pocket opening next to the pocket edge (26), formed on the internal circumference (U.sub.i) of the brake ring, creating a radial distance (b) between the cover (12) and the brake ring (14). The pocket edge (26) is surrounded by the cast cover (12) and the pockets (22) are substantially filled with the cast aluminium alloy. Because of this method of connecting the brake ring (14) to the cover (12), umbrella-like distortion can be largely avoided.
