An example of a material with a large damping capacity is gray cast iron.
2.
The block itself is an extra rigid, gray cast iron with a closed deck.
3.
Molds made from gray cast iron can be more economical to produce but have short mold lives.
4.
Unlike gray cast iron, which forms graphite flakes, ductile iron contains graphite nodules, or pores, which make cracking more difficult.
5.
It comprises predominantly a gray cast iron tube and was frequently used uncoated, although later coatings and linings reduced corrosion and improve hydraulics.
6.
Most materials shrink as they solidify, but, as the adjacent table shows, a few materials do not, such as gray cast iron.
7.
Note that not all elastic materials undergo linear elastic deformation; some, such as concrete, gray cast iron, and many polymers, respond in a nonlinear fashion.
