Since magnesium evaporates at high temperature, magnesium alloys are usually used to add magnesium to the melt. Adding ferrosilico magnesium to cast iron and steel alloys, in addition to spheroidizing graphites, increases impact resistance in casting parts and increases strength. This product is added in the mold a little before pouring, and the magnesium is absorbed by the graphite buds and becomes uniform in all directions by changing the surface tension of the growth conditions. Therefore, the elastic modulus, percentage of relative length change (elongation) and ultimate tensile strength (UTS) are improved in the parts.
Application: production of ductile cast iron and cast iron with compressed graphite
