Wang Zehua(Mechanoelectronics College,Hehai University,213022 Changzhou,China)  
It is outlined the development of ADI,and its features,such as good comprehensive mechanical properties,high fatigue strength,good fiction and wear characteristics.the coomon standards of ADI are also introduced.Addressing the poor machinability of ADI,it is pointed out the key to producing good quality ADI is:compact and even structure,good nodularization,a large amount of graphite,reasonable chemical composition,low segregation of elements,and correct parameters for heat treatment and wellcontrolled cooling condition for quenching.
