Pump Parts - Ductile Iron

Ductile iron is a cast iron that is solidified with a certain amount of nodularizer (rare earth magnesium alloy, etc.) and a small amount of inoculant (ferrosilicon or silicon-calcium alloy) before the molten iron is cast to obtain spheroidal graphite. It is the best performing cast iron and is increasingly used.
