31. Antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low boiling point. However, it is also like a metal because of its shiny silver appearance and ability to form alloys. Into which group should antimony be placed? 32.
Antimony (Sb) is an element that is blended in with metals such as lead to create different alloys. In lead-based alloys, antimony is added in the range of 1/2 percent to 12 percent and most commonly it is used in a range of 1/2 percent to 6 percent antimony and the balance of the alloy is lead or tin.o what does this do to the density? Pure lead has a density of .41 pounds per cubic inch. Six percent antimonial lead has a density of .393 pounds per cubic inch, which is a loss of .0028 per percentage point of antimony.
