The high Electrical & thermal conductivity of Copper Tungsten

  • Tungsten is a silvery white, lustrous (in one piece) or grey (powder
    form) heavy metal, which is hard and brittle but can be made stretchable
    by hammering or, drawn to form thin wires. Tungsten is characterised
    by its high melting point, good thermal conductivity, corrosion
    resistance and low thermal expansion. Tungsten is suitable for resistant
    heating elements, filaments (high temperature furnaces, electrical
    engineering), evaporation boats, in evaporation systems engine parts,
    x-ray anodes and welding electrodes. Tungsten rods can be melted into
    high-melting glasses to add electrical conductivity. Tungsten is used in
    nuclear engineering. Tungsten alloys are used about 80 % in the steel
    industry and approximately 10 % each in the hard metal industry and
    electrical engineering.


    The high electrical and thermal conductivity of tungsten copper alloy
    allows a cool, effective transfer of power, while the excellent
    arc-resistance properties of tungsten copper minimize arc erosion and
    transfer problems.


    The high Electrical & thermal conductivity of Copper Tungsten
    are combined with the arc-resistant & non-welding properties of
    tungsten or their carbides to form an extensive series of compositions
    each designed to give the best performance for your particular
    application. These materials are used for such heavy duty contact
    applications as:


    *Circuit breakers, air & oil immersed


    *Arcing tips or arc runners


    *Make & break contacts


    *Heavy duty conductors, relays & switches.
