Abstract

Procedure for preparing an alloy for the treatment of cast iron with spheroidal graphite, characterized in that iron, silicon, an alkaline-earth metal and nitro are mixed in the following proportions of 40 to 55% by weight of Si; from 3 to 15% by weight of Mg, from 1.4 to 8.6% by weight of Ba, and the rest being Fe and the inevitable impurities introduced during processing at a total concentration of less than 2.5%, the Mg/Ba weight ratio of 1 to 3, nitrogen is introduced into the mixture in an amount such that the Ba/N weight ratio is between 5 and 50.
