TOXICOLOGICAL PROFILE FOR ANTIMONY AND COMPOUNDS

Antimony metal is too easily broken to be used much by itself. To make it stronger, a little antimony is usually mixed with other metals such as lead and zinc to form mixtures of metals called alloys. These alloys are used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, type metal, ammunition, and pewter.

Sucess mixing tin and antimony to pure lead

Oct 28, 2013· So what you mixed up was 91-4.5-4.5 more less. It does help to have a concentration of tin in the mix before adding antimony. There is a way to use less tin and get the same results if you want. You could mix 2 pounds tin, 6 pounds antimony and only 14 pounds lead. This will make 9-27-64 tin/antimony/lead.

Antimony - Wikipedia

Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
