This calculator calculates the final alloy density from mixing together pure metals or other metal alloys of known weights and densities. The final alloy density calculated is an approximation of the actual alloy density. Please see "Examples" page for a discussion of this. The required values are the weights and densities of the starting pure metals or other metal alloys. Weight can be in any unit like grams or pounds provided only one weight unit is used. Percentage by weight or parts by weight can also be used. Density can be in any unit like lb/cubic inch. or gm/cubic cm or gm/ml provided only one density unit is used. Click on the add rows botton to add more entries. The number of decimal places for the calculated final alloy density can be specified (The default value is 5).
