Grey cast iron has a very high wear resistance with unusually good absorption characteristics in relation to mechanical oscillations. Grey cast iron can be cut well and casted excellent. These characteristics grow grey cast iron to one of the most economical cast materials at all. Therefore grey cast iron belongs to the usually-used iron-carbon-cast alloys today.

Grey cast iron graphite is present in the form of lamellas. In the cast iron the lamellas form a three-dimensional, branched out structure (photo right). This structure is decisive for the particularly good absorption characteristics, but also for the bad elongation of this material.
