Lead is the denser element
Aluminum
Sure, no problem there. They wouldn't be a particularly good choice though, as they'd be a lot lighter than lead bullets. Lighter means they'll slow down faster. You get less range and less penetration from the weapon.
Aluminium. Zinc is around two and a half times heavier (more dense) than Aluminium.
Aluminum is actually lighter than titanium
Aluminum, being a lighter element, rose toward the surface of the early molten Earth.
No, lead is more dense than aluminium.

Aluminum is the lighter than mercury.
Magnesium is lighter. As long as it's also strong enough it can lead to a lighter end product.

This mixture could be used in applications where both the weight of lead and the lighter weight of aluminium are desired. One common use is in shotgun ammunition, where the lead provides density for stopping power and the aluminium reduces recoil. It is important to handle lead with caution due to its toxicity.
Carbon fiber would be lighter than the same structural rigidity in aluminum
because it lighter
Aluminum is lighter than most other metals.
Aluminum radiators are lighter and cool almost as good as a copper/brass unit does. If they are both new then copper is going to cool better ,but the aluminum is up to 60% lighter.
