Find the reciprocal of the specific gravity of each metal in the alloy. This is done by dividing 1 by the specific gravity. For example, the specific gravity of silver is 10.49 and the reciprocal is 1 divided by 10.49 or 0.094966. Multiply each reciprocal by the number of parts per thousand of that metal to be used.

Jun 04, 2016· Specific gravity is a way to determine the density of an object—or in this case, a coin. The denser an object is, the heavier it feels. In plain language, the density of an object describes how many molecules are packed together in the area. Since gold is one of the densest materials, gold feels heavier than it looks.
