The densities of the three most commonly used materials for weights are as follows:
Zinc - 445lbs./cu.ft.
Zamac (a zinc alloy) - 407lbs./cu.ft.
Steel - 490lbs./cu.ft.
The density of lead is 709lbs./cu.ft.
Not only is the lead denser, it's also easier to work with: cutting, filing, casting, and malleating (beating into shape with a hammer) can be done with simple tools that most people would have on-hand.
