Master alloys - intermediate alloys containing a large amount alloying metal which added to the melt to obtain the desired chemical composition, improved structural and technological properties of castings and ingots.

The alloying tablets or briquettes - metal powders, compacted into cylindrical tablets intended for alloying of aluminum alloys.

Ferroalloys - iron alloys with other elements - Molybdenum, Tungsten, Titanium, etc. They are used for ligation to impart certain properties of the metal.
