Abstract

The development of advanced technology at this time requires good quality materials, especially those made from metal. Mechanical properties of metal materials such as: hardness, plasticity and wear. To improve the properties of metal materials, it is necessary to add alloy elements to the composition of metal materials. This encourages the need for research. This study uses the main material FCD cast iron with ferro silicon magnesium alloy elements (FeSiMg). This study aims to find out the effect of variations in magnesium (Mg) on microstructure, tensile strength, yield strength and modulus of elasticity. ferro silicon magnesium (FeSiMg) variations which are added as much as 50 grams, 100 grams, 150 grams, 200 grams in raw material in the form of FCD on ladels 15 kg. Each variation produces a percentage of magnesium (Mg) specimens 2, 3, 4, and 5 respectively 0.0307%, 0.0336%, 0.0343% and 0.0351%. From the results of microstructure testing, the more magnesium elements, the graphite granules produced tend to be more uniform and shrink, more pearlite and less ferrite. From the tensile test it can be concluded that the test results on specimens of 1 raw material FCD and specimens 2, 3, 4, 5 resulting from variations in the elemental content of magnesium produce a value of increased strength and stiffness
