Lead tin alloy can be divided into:
① Lead base or tin base bearing alloy. And lead base bearing alloys are collectively referred to as Babbitt alloys. It contains 3% ~ 15% antimony and 3% ~ 10% copper. Some alloys also contain 10% lead. Antimony and copper are used to improve the strength and hardness of the alloy. It has small friction coefficient, good toughness, thermal conductivity and corrosion resistance. It is mainly used to manufacture sliding bearings.
② Lead tin solder. It is mainly tin lead alloy, and some tin solders also contain a small amount of antimony. Tin alloy containing 38.1% lead, commonly known as soldering tin, has a melting point of about 183 ℃, which is used for the welding of components in the electrical instrument industry and the sealing of automobile radiators, heat exchangers, food and beverage containers.G90 G50 Best Quality 28 gauge corrugated steel roofing sheet
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 system, tin nickel system coating, etc.Mild steel rectangular pipe
④ Lead tin alloy (including lead tin alloy and lead-free tin alloy) can be used to produce all kinds of exquisite alloy jewelry and alloy handicrafts, such as rings, necklaces, bracelets, earrings, brooches, buttons, tie clips, hat decorations, craft decorations, alloy photo frames, religious emblems, miniature statues, souvenirs, etc.china promotional hot rolled channel steel specifications
