Electrical contacts

The physical and mechanical properties and melting point of tungsten copper alloys electrical contacts material will be positively or oppositely affected by varying the amount of copper tungsten in the composite.  As the copper content gradually increases, the electrical and thermal conductivity and thermal expansion exhibit a tendency of being stronger, but the density, electrical resistance, hardness and strength will be weakened when infiltrated with less amount of copper. In the end, an appropriate chemical composition is the utmost importance when considering tungsten copper for specific application need.
