Nickel-magnesium master alloy

Master alloys of the nickel-magnesium group are used as modifiers in the casting of cast iron of various grades. They are also used for the desulfurization and deoxidation of special steels and superalloys. It is possible to add the rare earth element cerium to the nickel-magnesium master alloy.

The NiMg master alloys are added into the base metal during its melting. As a result, the efficiency of Mg uptake in liquid iron is significantly improved (compared to the addition of pure Mg). The high density of the nickel-magnesium master alloy makes it possible to add it to the melt in the simplest way, providing a stable and reliable modification result. In this case, the evaporation of MgO and the pyroelectric effect are minimized.

  

The main features:

The nickel-magnesium master alloy is made from high purity metals, as a rule, from magnesium of the Mg99.90 grade and nickel of the N1, N1U grades. Depending on the brand of the ligature, the magnesium content is in the range of 4–22%, the rest is nickel. The total content of impurities does not exceed 0.5%. The density of the standard modifier NiMg 15% is about 6 g/cm3, the melting point is 1,100 °C.

Along with the main elements - magnesium and nickel - the composition of alloys, in agreement with customers, may include additives of cerium, iron and other elements. Nickel-magnesium products containing cesium or other rare earth metals with similar properties are also on the market today. The presence of these elements neutralizes the possible harmful effects of other impurities.
