Lead (Latin: Plumbum) is one of the oldest metals used by humans, known since around 6400 BC. It is a very soft and easily workable metal that can be easily cast, rolled, and shaped. Lead is characterized by high density, corrosion resistance, and relatively low thermal and electrical conductivity. Its melting point is 327.5 °C, and its boiling point is 1744 °C.
Lead (chemical symbol Pb) is a toxic metal, and its use is restricted or banned in many industrial applications. However, due to its durability and resistance to environmental factors, it is still widely used in specific sectors. The most common application is in lead-acid batteries, where a single unit may contain approximately 7–9.5 kg of lead.
Due to its high density, lead is used in radiation shielding (e.g., X-ray protection). It is also used in various metal alloys. Molten lead is used in processes for extracting precious metals such as gold and silver.
