Abstract

The invention relates to an alloy for modifying iron containing silicium, strontium, calcium, aluminium, zirconium and iron and additionally containing magnesium and rear-earth metals at a following component ratio: 45-78 mass % silicium, 0.1-2.0 mass % strontium, 0.1-0.15 mass % calcium, 0.3-0.2 mass % aluminium, 0.1-2.0 mass % zirconium, 0.1-7.0 mass % magnesium, 0.1-2.2 mass % rare-earth metals, the rest being iron. An alloy used for iron graphitizing processing contains 0.1-1.0 mass % magnesium, 0.1-0.2 mass % calcium, 0.3-0.5 mass % aluminium and 0.1-0.3 mass % rare-earth metals. An alloy for graphitizing and spheroidizing iron processing contains 4.0-7.0 mass % magnesium, 0.2-1.0 mass % calcium, 0.5-1.5 mass % aluminium, 0.1-0.3 mass % zirconium, rare-earth metals are represented by individual elements in the form of lanthanum and neodymium, wherein the total quantity thereof ranges from 0.2 to 0.5 mass %. The inventive alloy makes it possible to remove chilling on thin-walled casting, increase the iron strength and plasticity and to ensure the modifying effect reproducibility.
