Abstract

Nodular cast iron is a type of round cast iron graphite. Magnesium (Mg) is the element most often used in the world of the casting industry as a graphite rounder because it is more profitable than other elements. This study aims to determine the effect of nodular cast iron magnesium (Mg) variation on the microstructure, Mg composition, phase configuration, graphite and its matrix. This study uses FCD as a starting material which is then melted in the melting furnace. The process of forming a round-shaped cast iron is carried out with an open ladel system, which is a variation of 50 grams, 100 grams, and 200 grams of FeSiMg which is placed at the base of a 15 kg capacity ladder just before the liquid iron is poured in ladels. Based on the results of the study, data analysis and the results of the discussion on the Surface Analysis of the Nodular Cast Iron Impact Test with Variations in Magnesium Content (Mg) of 50 grams, 100 grams, 200 grams, the more FeSiMg additions, the magnesium (Mg) content increases from specimen 1 (Mg) 0.0307%), specimen 2 (0.0336%) and specimen 3 (0.0351%).
