Lead is primarily used in the manufacturing of car batteries (lead-acid batteries), which constitute around 80% of industrial lead usage[1][3]. It is also widely used for radiation shielding in medical facilities, nuclear power plants, and X-ray environments, due to its ability to absorb harmful rays[1][2][5].
Other common uses of lead include:
- Production of cable sheaths and wiring insulation, although this practice is declining due to toxicity concerns[1][3].
- Manufacturing of alloys (such as tin-lead alloys) for solder, bearings, fusible alloys, and pewter, enhancing resistance to breaking and cracking[1][2][3].
- Use in shipbuilding to protect metals from corrosion, with thick lead sheets serving as a shield[1][3].
- Production of lead oxide, used in batteries, glass, ceramics, rubber vulcanization, and as additives in paints and coatings[1][3].
- As ammunition (bullets and shot pellets) due to its density and malleability[2][3].
- As weights for equipment balancing and marine ballast due to its high density[7].
- In construction, such as roofing materials, pipe linings, and corrosion-resistant water pipes (usage now reduced for health reasons)[2][5][8].
Additional minor uses include cultural items, lighting, noise and vibration dampening in machinery, and limited die-casting applications. However, due to its toxicity, many uses—especially in consumer products, pipes, paints, and solders—have been severely restricted or replaced in modern industry[5][7].
