Bronze is an alloy of Copper with the addition of tin, arsenic, phosphorus, aluminum, manganese, and silicon.  The additions produce and alloy much harder than copper alone.  Early Bronze was created from copper and arsenic, and later tin and arsenic.  Scientific Testing is needed to show what type of alloying agent is being used.
