The time period of a simple pendulum is given by
  T=
                 2\pi \sqrt{\frac{l}{g}}
It is independent of any intrinsic property of a material. Thus, time period will remain same both for a wooden bob and an iron bob.

Since the sizes of metal bob and wooden bob are equal, the position of centre of mass does not
change. Therefore the length of the pendulum remains same so, time period remains constant.
