Definition Of Fusible Alloys

Fusible alloys refer to alloys with melting points lower than 232°C. It is a kind of fusible alloy based on bismuth element, which is a gray-white shiny metal. The melting point is 47°C, 70°C, 92°C, 120°C, etc.; the low melting point alloy can be melted by the water bath method or the oil bath method. The strength is 30MPa at room temperature, the elongation is 3%, and the hardness is 25HBS.

Fusible alloys are often widely used as solders, as well as heat-sensitive components such as fuses and fuses in electrical appliances, steam, fire protection, fire alarms and other devices. Generally, the melting point of bismuth-tin low-melting alloy is only 70-160 °C, and it has good fluidity after heating and melting. Therefore, this type of low-melting metal is also widely used to make molds by casting, and fusible alloys are used in molding. The mold cycle is short, the machining time is less, and the advantages are obvious. In addition, fusible metals are also widely used in medicine to make blocks for radiotherapy. Blocks made of low-melting alloys can effectively block normal human tissues during radiotherapy. The method of making blocks from fusible alloys effectively improves the Accuracy and safety of radiation therapy.
