Experiments on irradiation of copper alloys Cu-4%Ni and Cu-4%Ni-10%Ga (mass %) by powerful pulsed deuterium plasma (DP) and deuterium ion (ID) flows were carried out in the Plasma Focus (PF) facility. It is noted that the studied ductile copper alloys of the Cu-Ni and Cu-Ni-Ga systems, as well as the previously studied Cu-10% Ga alloy, exhibit a very high crack resistance to the impact of powerful pulsed radiation-thermal loads generated in the PF installation, in comparison with refractory metals - W, Mo, V.
