Structure, corrosion resistance, and mechanical properties of Cu‒W composite materials used for various-purpose electric contacts were studied. Shown is the influence of tungsten concentration in Cu‒W composite material on these properties. Gravimetric dependencies of Cu‒W composite materials with different tungsten content are given and composition of the corrosive environment before and after corrosion testing is determined.
