Lead/tin alloy is a type of metal alloy composed of lead and tin. It is most commonly used in the form of terne, calin, and SOLDER. Terne is a lead-tin alloy that is used for coating steel sheets and is known for its corrosion resistance. Calin is a lead-tin alloy that is used for soldering and brazing and is known for its low melting point. SOLDER is a lead-tin alloy that is used for joining electrical components and is known for its electrical conductivity. Lead/tin alloy is a versatile material that is used in a variety of applications.
