Antimony Properties

Jul 22, 2009 · Antimony is typical in this regard as its electrical conductivity is only 1/27 that of copper. Antimony is atypical compared with other metals because it is fragile, readily fractures, is not malleable, and can be easily powdered. Interestingly, antimony loses mechanical strength as its purity increases.
