In the aspect of high strength low alloy ductile iron, in addition to copper and molybdenum, nickel and niobium are also studied. Although the properties of medium manganese nodular cast iron are not stable enough, its systematic research and production application over the years have achieved remarkable economic benefits.

In addition to Medium Silicon Ductile Iron, the effect of Si + Al content on the growth resistance of RE Mg ductile iron was studied. The service life of rqtal5si5 heat-resistant cast iron developed in China is three times of that of grey cast iron, two times of that of ordinary heat-resistant cast iron, and the same as that of Japanese heat-resistant steel.
