Abstract:
1. An aluminum-based master alloy for manganese alloying of metal alloys, wherein the master alloy is an aluminum-manganese alloy, comprising optionally of other components, wherein the master alloy is made in the form of splatters and with transformations in a crystal structure at an alloying temperature, wherein the master alloy comprises of, in mass %: Mn—77.0-93.0; other components, incl. Fe and Si, each not more than 2.0, in total not more than 5.0, where Fe—not less than 0.01 and Si—not less than 0.01; Al—rest up to 100; and the alloying temperature is in the range of 650-850° C. wherein the splatters have thickness in the range from 1 mm to 10 mm.
