SPHEROIDAL GRAPHITE IRON/DUCTILE CAST IRON ALLOY/NODULIZER ALLOY AND A PROCESS FOR MANUFACTURING THE SAME

摘要

A Ni-free, copper based, non-ferrous nodulizer alloy for the production of high strength, high ductile spheroidal graphite iron is disclosed. The nodulizer alloy of the present invention is economical, efficient, produces pearlitic grade spheroidal graphite iron with uniform and controlled microstructure and can be used for any method of Mg treatment for the production of spheroidal graphite iron.
