1. Batteries: Lead-acid batteries are the most common type of battery used in automobiles, motorcycles, and other vehicles. These batteries use lead plates as electrodes and sulfuric acid as an electrolyte.

2. Radiation shielding: Lead is often used as a shielding material in radiology, nuclear medicine, and other industries that use radioactive materials. Lead shielding can help protect workers and the public from exposure to ionizing radiation.

3. Plumbing: Before the dangers of lead were well understood, it was common to use lead pipes and solder in plumbing systems. Today, most plumbing systems use safer materials like copper or plastic.

4. Ammunition: Lead is commonly used as a material for bullets and shot in firearms.

The use of lead in manufacturing has been declining in recent years due to concerns over its toxicity and the development of safer alternatives. However, it is still an important material in certain applications, particularly in the automotive and battery industries.
