Correlation relations between the strength and the electrical conductivity of aluminum shapes are determined. The properties of alloy V95ochT2 are studied after different temperature-and-time actions. It is shown that the “dark spots” appearing on the surface of such shapes can be evaluated by a nondestructive eddy-current method.
