Lead is the denser element
Lead (Pb), with a density of 11,34 g/cm3.
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.
Lead
no because the molar mass of lead is great than aluminum
Lead
No, lead is more dense than aluminium.
Aluminum
Magnesium is lighter. As long as it's also strong enough it can lead to a lighter end product.
Aluminum is the lighter than mercury.
no
Carbon fiber would be lighter than the same structural rigidity in aluminum

separate mixtures into their componets lead and aluminum pellets
because it lighter
Lead
Lead will always have the greater density compared to aluminium. The weight only influences the volume in question. 10kg of Al will be much more(bigger in size) than 5kg of lead.
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.
