Product Description

Bismuth CAS 7440-69-9 Bi Raw Earth




Bismuth is a silver white to pink metal, which is brittle and easy to be crushed. Its chemical properties are relatively stable. Bismuth exists in nature in the form of free metals and minerals. Previously, bismuth was considered to be the most stable element with the largest relative atomic mass, but in 2003, it was found that bismuth has extremely weak radioactivity.

It can be made into target, bar, particle, wire or processed according to customer's requirements.




Melting point 271 °C(lit.)
Color Silver white or reddish




Bismuth is mainly used to make fusible alloys. The melting range is 47-262 ℃. The most commonly used alloy is bismuth, which is composed of lead, tin, antimony, indium and other metals. It is used for the safety plug of fire-fighting device, automatic sprinkler and boiler. In case of fire, the piston of some water pipes will melt automatically and spray water. In fire protection and electrical industry, it is used as automatic fire extinguishing system, electrical fuse and soldering tin. Bismuth alloy has the characteristics of non shrinkage during solidification, and is used for casting printing type and high-precision mold. Bismuth oxycarbonate and bismuth oxynitrate are used to treat skin injury and gastrointestinal diseases.

It has special importance in fire protection and electrical safety devices.
