Melting point: 138℃
Hardness: 1.92 Mohs
Composition: tin, bismuth, plus other auxiliary metals.
At room temperature, tin-bismuth alloy is solid and silver-white, with low melting point, low hardness, solid-liquid volume shrinkage rate of 0.051%, and strong permeability.
The main uses of tin-bismuth alloy:
1. It is used for electroforming production of gold, copper and silver jewelry and handicrafts.
2. Precision inspection of metal molds.
3. Fusible alloys are widely used as solders;
4. Fusible alloys are used in thermal components such as fuses and fuses in electrical appliances, steam, fire protection, fire alarm and other devices;
5. Fusible alloys are used in medicine to make blocks for radiotherapy;
6. Fusible metals are used as fillers when bending metal pipes;
7. Fusible metals are used as inlays when making metallographic samples.
8. Fusible alloys are used for plugs of automatic sprinkler systems.
Preparation of tin-bismuth alloy and its main physical properties
Put the tin-bismuth alloy into a pot or other heating vessel that has been heated to 350°C. During its melting process, it should be stirred continuously until uniform. If there is scum, remove it. Then, the homogeneous alloy melt is poured into strips in angle steel or channel steel for use in pouring samples.
