Classification Of Lead txo tin Alloys

① Lead reduce based or tin reduce based bearing alloys. Alloys with lead reduce based bearings are collectively referred to as babbitt alloys. It contains 3 percent to 15 percent of antimony, 3 percent to 10 percent of copper, and some alloy varieties also contain 10 percent of lead. Antimony and copper are used to improve the strength and hardness of the alloy. It has a small friction coefficient, good toughness, thermal conductivity and corrosion resistance, and is mainly used to manufacture sliding bearings.

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

③ Lead reduce 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 reduce lead and tin reduce nickel coatings.

④ Lead reduce tin alloys (including lead reduce tin alloys, lead reduce free tin alloys) 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 ornaments, craft pendulums ornaments, alloy photo frames, religious emblems, miniature statues, souvenirs, etc.
