What is Strength of Copper Alloys - Definition | Material ...

Copper alloys are alloys based on copper, in which the main alloying elements are Zn, Sn, Si, Al, Ni. Cu-based alloys constitute mostly substitutional solid solutions, for which solute or impurity atoms replace or substitute for the host atoms.Several features of the solute and solvent atoms determine the degree to which the former dissolves in the latter.
