"Lead Wire" refers to lead wire—a filamentary metal product made from pure lead or lead alloys (e.g., adding elements like tin and antimony) through a drawing process. Its core characteristics include radiation protection, corrosion resistance, and easy processability, making it widely used in medical, electronic, chemical, and other fields.

The selection of lead doors in medical CT rooms is of crucial importance, as they not only provide radiation protection but also serve as sealing materials to prevent the leakage of liquids or gases.

Lead ingots are divided into large ingots and small ingots, mainly used in the manufacturing of storage batteries, coatings, bullets, welding materials, lead salts for chemicals, cable sheaths, bearing materials, caulking materials, Babbitt metal, and protective materials for X-rays.
