If the amount of copper is high and the alloying elements are close to copper in density, the density of the alloy will not differ much from pure copper. Electrical resistance is one way of differentiating the pure copper from alloys. If the components are of the same shape and size, a simple multipmeter will do to differentiate the resistance.
