The results of experimental researches of laws of propagation of films on the surface of the con- densed alloys of copper are considered at various external influences. The optical parameters (n and k) for Сu-Sn alloys are determined to have the maximum in the range of 38 42% Sn. At cyclic tempera- ture influences on Cu-Ni alloys the steady oxides NiO are formed ensuring reliable protection of an original material with the subsequent influences of the atmosphere. The explanation to the laws ob- served is offered. The questions of use of condensed films of copper alloys in products of electronic en- gineering are discussed.
