For every 1% additional antimony, Brinell hardness increases 0.9. For a simple equation, Brinell = 8.60 + ( 0.29 * Tin ) + ( 0.92 * Antimony ) When you know the percentages of Lead, Tin and Antimony in an alloy you can easily and accurately determine the as cast and air cooled BHN hardness of the alloy by the formula.
