锻件需要每片都是一致的，没有任何多孔性、内含物或其他的瑕疵。这种方法生产的元件，强度与重量比有一个高的比率。这些元件通常被用在飞机结构中。
Forgings need to be consistent with each piece, without any porosity, inclusions or other defects. The components produced by this method have a high ratio of strength to weight. These components are usually used in aircraft structures.
锻件的优点有可伸展的长度、可收缩的横截面;可收缩的长度、可伸展的横截面;可改变的长度、可改变的横截面。锻件的种类有:自由锻造/手锻、热模锻/精密锻造、顶锻、滚锻和模锻。
Forging has the advantages of stretchable length and shrinkable cross section; shrinkable length and stretchable cross section; variable length and variable cross section. The types of forgings are: free forging/hand forging, hot die forging/precision forging, upsetting, roll forging and die forging.
