Refers to a group of colored crystalline compounds of variable composition with a distinctive surface sheen, which represent the mixed oxides of tungsten, sodium or other alkali metal. Such materials are good conductors of electricity. They can be obtained by reduction of the normal tungstate (in the form of sodium tungstate Na2 WO4 with tungsten) or tungsten trioxide with sodium. Tungsten bronze is a metal composite material, which consists of a combination of tungsten and copper. Production their production process is hot extrusion of tungsten in the melt. The result is a relatively hard material with excellent electrical and mechanical resistance and wear resistance, high physical properties at elevated temperatures and good electrical and thermal conductivity.

The use of tungsten bronze electrodes for resistance welding, heat sinks as passive cooling elements of electronic devices electrodes in installations of electro-spark processing, closing contacts and vacuum contacts in circuit breakers high and medium voltage in vacuum.
Lead (vincolata) bronze is used in lead-acid batteries, fire sprinkler systems, in the production of munitions, cable shells and some building materials. (such as sheet, pipe, solder, and wool for sealing).
