Lead isn't "made out of" any other metals. It's an element.
Depends what kind you have. Many have lead, but some contain iron, or other heavy weight metals.
The positive electrode is made of lead oxide, the negative of any of the following metals: iron, lead, zinc or cadmium. The electrolyte can the hydroxides of any of the alkali metals (such as sodium). Please see the link.
iron, lead other metals that are not alloys
Most are. A very few have no lead, but most bullets ARE lead, or lead combined with other metals. A few have been made of plastic, wood, wax, copper, steel and even powdered iron.
both are metals
Lead. The densities of lead and tin are 11.34 g/cm^3 and ~7 g/cm^3, respectively. Lead solder is an alloy made of mostly lead and tin; a mixture of lead and tin will weigh less than 100% lead. Lead-free solders are made of tin, copper, silver, indium, bismuth, zinc, antimony, and other metals; none of these metals is heavier than lead. So, lead is the champion.
Various metals and wood
The best rings are made out of precious metals.
There are three metals used in wheel weights, steel, zinc and lead. Steel and zinc are hard metals, and lead is a soft one. I would clamp the weight in question in a vise and try to bend it; if it can be bent fairly easily, it's lead.
They are mostly made of graphite which is a stable form of carbon :)
no lead is an element
Most are made from one or more metals, including lead, lead covered in a brass alloy, copper, etc. A few bullets are made of a hardened steel with a brass covering, and a few from plastic.
