The results of examinations of legitimacies of forming of structure in condensed systems Cu-Sn and their analogs are given. The features of forming of intermetallic compounds in massive and in condensed systems are considered. The intermetallic compound Cu-Sn, formated on the average range of concentrations Sn (about 3845% Sn on mass) has the highest corrosion-electrochemical performances.
