I know structural steel is considered to have an elastic behavior and after a certain deformation, it has a plastic behavior.

How about gold metal?

  • $\begingroup$ Gold has similar behaviour, try searching "gold mechanical properties" for more. $\endgroup$

    $\begingroup$ Technically, all materials have some degree of elasticity. That is a different matter from whether a material makes a viable spring, however. $\endgroup$

Gold has a Young's modulus of 79 GPa which is very similar to silver, but significantly lower than iron or steel.

  • $\begingroup$ Right. Steel has a Young's modulus of 200 GB. Almost 2.5 times that of gold. $\endgroup$

  • $\begingroup$ Interestingly, steel density is almost 2.5 times less than gold. $\endgroup$
