Stiffness (Young's Modulus)
Rigidity, also known as "stiffness," is generally measured using Young's modulus. It can be defined as the "force necessary to bend a material to a given degree."
As shown in the graph below, Fine Ceramics are highly rigid materials, according to Young's modulus. This makes their machining accuracy high enough to enable them to be used for high-precision parts.
