Conclusions
-
1.
We investigated the effect of niobium (up to 1.5%) on the mechanical properties, heat resistance, and electrical resistivity of copper.
-
2.
The properties of Cu−Nb alloys do not depend on the heat treatment conditions, which distinguishes the alloys of this system from most of the thermal conducting and electrical conducting alloys used at the present time.
-
3.
With increasing concentrations of niobium the red hardness of the alloys increases continuously and exceeds that of copper by a factor of 2–3. The electrical conductivity decreases slightly.
-
4.
Copper alloys with 0.2–0.75% Nb can be recommended for parts and structures in a wide range of operating temperatures where heat treatment is technically difficult or impossible.
