Abstract
The present invention provides a rapidly dissolving additive for metal melts, wherein it contains or consists of 2 to 50% by weight of a powdered component A, consisting of magnesium and/or a magnesium-containing alloy, and 50 to 98% by weight of a powdered component B, consisting of one or more alloying metals, the components A and B being intimately mixed and being present in pressed or compacted form.
Claims18
A process for the introduction of alloying metals into melts of aluminum, aluminium alloys, magnesium or magnesium alloys, said process comprising adding to the melt a composition comprising from 2 to 50% by weight of a powdered component A, consisting of magnesium and/or a magnesium-containing alloy, and 50 to 98% by weight of a powdered component B, consisting of one or more alloying metals, the components A and B being intimately mixed and being in pressed or compacted form.
In a process for producing metal alloys, wherein a solid alloying element is added to a molten metal bath, the improvement wherein the solid alloying element is in the form of a rapidly dissolving additive comprising 2 to 50% by weight of a powdered component A which consists of magnesium or a magnesium containing alloy, and 50 to 98% of a powdered component B which consists of the alloying element, the component A and B being intimately mixed and in pressed or compacted form, said additive being present in an amount of from 0.1 to 25 wt. % of the molten metal.
