Because it just does. Alright, I will give a much more detailed explination...
The atoms inside the Lead have a source of meacliocional spacing (something that will makes atoms tightly packed up like you being squished in the crowd of getting in the number 1 bus in London), and it means more space for the atoms. Aluminium on the other hand, has a little spacing between atoms, and therefore I conclude that Lead is heavier than aluminium because of the fact of lack of meacliocional spacing.

Aluminum has about 1/3 the density of iron, therefore a given volume of aluminum would weigh about 1/3 as much as the same amount of iron. So no, aluminum is not heavier than iron; far from it.
Stainless steel is heavier then aluminium.
Lead is about 20% denser than iron, but its exact weight depends on the specific alloy or form of each metal. However, lead is generally heavier than iron.
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
At "normal" temperatures, Mercury is denser than any of those substances ... slightly more so than lead, somewhat more so than copper, and a lot more so than aluminium.
Lead
Ice is heavier than aluminium. You may think that ice is just water really it holds more (volume) than aluminium.
Iron is heavier than aluminium. Aluminium is easier to form, shape and machine.
Aluminum has about 1/3 the density of iron, therefore a given volume of aluminum would weigh about 1/3 as much as the same amount of iron. So no, aluminum is not heavier than iron; far from it.
Lead is much heavier than stainless steel.
no lead is heavir because it contains more weigh no lead is heavir because it contains more weigh
Iron has a higher density than aluminum
No, lead is heavier than platinum. Lead has a higher density and atomic weight compared to platinum.
tungsten is more more heavier han the lead as it has great mass in less volume
Yes, by about 8.2%. (rounded)
No, lead is more dense than aluminium.
Yes, uranium is more dense (heavier) than lead.
