Classification Of Lead-tin Alloys

② Lead-tin solder. Mainly tin-lead alloys, and some tin solders also contain a small amount of antimony. Tin alloy containing 38.1% lead, commonly known as solder, has a melting point of about 183°C.

③ Lead-tin alloy coating. Using the corrosion resistance of tin alloy, it is coated on the surface of various electrical components, which is both protective and decorative. Commonly used are tin-lead and tin-nickel coatings.
