Lead alloys are mixtures of lead with other metals, designed to enhance specific properties for various applications. Common alloying elements include tin, antimony, and copper, which improve strength, corrosion resistance, and malleability. These alloys are often used in batteries, radiation shielding, and soldering materials. The most well-known lead alloy is lead-tin solder, widely used in electronics for joining components. Another important type is lead-antimony alloy, which is utilized in battery grids due to its durability and conductivity. Overall, lead alloys play a crucial role in many industrial and commercial products.
