Uses and Properties:

• Bismuth is a soft, silvery metal with a bright, shiny surface and a yellowish or pinkish tinge.

• The metal breaks easily and cannot be fabricated (worked with) at room temperature.

• Its melting point is 271°C (520°F) and its boiling point is 1,560°C (2,480°F). Its density is 9.78 grams per cubic centimeter.

• Bismuth is a high-density, silvery, pink-tinged metal. 

• Bismuth metal is brittle and so it is usually mixed with other metals to make it useful.

• Its alloys with tin or cadmium have low melting points and are used in fire detectors and extinguishers, electric fuses and solders.
