Lead has a higher density and lower elastic modulus (the restoring force of atoms is less) compared to copper. Copper is more springy compared to lead.
Velocity decreases with density but is also affected by Elastic Modulus of the material. V = sqrt. E/d where E is the Elastic Modulus and d the density.

It is the density difference between the two metals. The alignment and number of molecules are different between lead and copper. (Remember the Periodic Table of the Elements?) Lead and Cooper have different atomic numbers.

Lead has a higher density, but is also a sifter material than copper is.

Atoms in lead are denser, more compacted together. This slows down sound waves

Atoms binded together more tightly?
Not sure.

because it has a higher density?
