Mechanical properties such as Bulk modulus, Third order elastic constants, pressure derivatives of second order elastic
constants and first pressure derivative of Bulk Modulus of many FCC metals such as Copper, Aluminum, Nickel, Silver and
Gold are carried out by taking K. D. potential. Potential parameters of these FCC metals are calculated by taking experimental
values of lattice parameter and second order elastic constants. Computed results of these mechanical properties are compared
with experimental and calculated results of other investigators. Our calculated results are fairly well agreement with
experimental results in comparison to computed results of other workers for all FCC metals except Gold.
