Lead-Tin Alloys
- May 09, 2017 -

Lead-tin alloys are divided into: ① lead or tin base bearing alloys. and lead-based bearing alloys are collectively referred to as Babbitt alloys. containing antimony 3%~15%, copper 3%~10%, some alloy varieties also contain 10% of lead. Antimony and copper are used to improve the strength and hardness of the alloys. Its friction coefficient is small, has good toughness, thermal conductivity and corrosion resistance, mainly used to make sliding bearings. ② lead-tin solder. The tin-PB alloy is mainly, some tin solder also contains a small amount of antimony. PB-38.1% of Tin alloys, commonly known as solder, melting point of about 183 ℃, used in electrical instrumentation industry components welding, as well as automotive radiator, heat exchangers, food and beverage containers sealed. ③ lead-Tin alloy coatings. The corrosion resistance of tin alloys is applied to the surface of various electrical components, both protective and decorative. Commonly used tin lead, tin ni coating, etc. Lead-tin alloys (including lead-tin alloys) lead-free tin alloy can be used to produce a variety of exquisite alloy jewelry, alloy crafts, such as rings, necklaces, bracelets, earrings, brooches, buttons, tie clips, hat ornaments, craft decorations, alloy photo frames, religious emblem, miniature statues, souvenirs and so on.
