Classification And Use Characteristics Of Lead-tin Alloys

There are 6 main types of lead-tin alloys: 1# lead-tin alloy, 2# lead-tin alloy, 3# lead-tin alloy, 4# lead-tin alloy, 5# lead-tin alloy, 6# lead-tin alloy Tin alloy. Among the six kinds of lead-tin alloys, the melting point of each material alloy is different, and the only thing they have in common is that they are all based on lead and tin, and then add different amounts of antimony according to their different uses. It is composed of some other trace metal elements. The following is a detailed description of these six materials.

1# Lead-tin alloy: This type of alloy is mostly used in the production of various high-end jewelry and handicrafts. Because such alloys have strong toughness, light specific gravity, and large smooth surface, their melting point is about 200 to 220 °C.

2# Lead-tin alloy: This type of alloy is mostly used in the production of various mid-range jewelry and handicrafts. Such alloys have better toughness and lighter specific gravity. Its melting point is about 230 ~ 250 ℃.

The 3# lead-tin alloy is mostly used in the production of various mid-range jewelry and handicrafts. Because such alloys have better toughness, lower density, lighter specific gravity and larger polished surface. Its melting point is 270°C,

4# lead-tin alloy: commonly used in various mid-range jewelry, because this alloy has good toughness and light specific gravity, its melting point is 280 ℃,

5# Lead-tin alloy: This kind of alloy makes various mid-range jewelry and handicrafts with good toughness, light specific gravity, narrow polished surface or no need to polish. Its melting point is between 280 and 290 °C.

6# Lead-tin alloy: This kind of alloy is slightly worse than the above, and can only be used for the production of some ordinary jewelry. Its melting point is 300-320°C.
