FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy of metals and alloys, namely, to production of aluminum alloys for alloying aluminum-based alloys containing refractory metals. Sintered ligature of powder materials for alloying aluminum alloys contains, wt%: molybdenum 40–50; copper 4.0–4.5; aluminum – balance.
EFFECT: invention is aimed at expansion of operational capabilities of ligature for melting of aluminum alloys due to improved distribution and increase rate of dissolution of alloying components in melt, improving stability of compositions of melted alloys with obtaining more accurate and homogeneous content thereof in the entire volume of the melt and the finished ingot.
