DESCRIPTION

Tungsten copper alloy are able to combining the high electrical conductivity of copper with the mechanical strength of tungsten. By infiltrating a tungsten skeleton with a copper wire, it is possible to combine the high melting point and mechanical strength of tungsten with the electrical conductivity of copper. In these combinations, copper is infiltrated with weight percentages ranging from 10% to 40%. They are typically used as high voltage electrical contacts, EDM electrodes and balance weights. In addition, their exceptional workability combined with good thermal conductivity and low thermal expansion allows many applications in different sectors: they are very resistant to electric arc, have good electrical conductivity, good thermal conductivity and low thermal expansion. There are several markets on which these alloys are applied: for example for lightning rods and power dispersion for wind turbines and in components for pantographs of trams and trams.
