Abstract
A compacted steel powder in particulate form is used as an alloying additive for aluminum melts. The additive is in the form of a wafer which is smooth on one side and corrugated on the other side such that its thickness is 1 mm at the trough and 2-3 mm at the peak. The shape of the additive results in dissolution of the additive in the aluminum melts at an equivalent rate as compared to a conventional briquette.
