Silicon Manganese Nodulizer supplies
Nodulizers are certain metals or alloys which added to molten iron to obtain spheroidal graphite cast iron. Additives that make crystallize graphite in cast iron into spherical shapes, called "nodulizers". The main components of the "spheroidizer" are spheroidizing elements, such as Mg, Ce, Ca, etc. China's commonly used is the nodulizer of ferrosilicon rare earth magnesium.
