    Tungsten rods are blanks that, in cross-section, are a circle, square, rectangle, hexagon, trapezium, segment or oval. The product is a semi-finished product, and is used to obtain various parts.

    Most often, the rods of tungsten alloys BA, BT, BL are used as non-consumable welding electrodes, when the parts are welded using solder. The heating elements of furnaces operating in vacuum, hydrogen and inert gas are produced from this material.

    Cathodes of radio tubes, electronic and gas-discharge devices are made of tungsten rods.

    Tungsten rods differ in a number of advantages:

    • high working temperature;
    • strength and hardness regardless of the aggressiveness of the environment;
    • high ohmic resistance;
    • significant modulus of elasticity;
    • creep resistance when exposed to high temperatures.

    tungsten rods can be made in accordance with several options:

    Alloy type Bars  dimensions, mm Base element, W, % Impurities, not more (%)
    BA diameter  – 3-10, length  ≥ 300 ≥ 99,9 Al, O each –  0,003; Fe, Ca each  –  0,01; Ni, Si each  –  0,005; Mo – 0,04; C – 0,008;
    N – 0,001; H – 0,0004
    diameter  – 1-12, length  300-1000 ≥ 99,95 Fe + Mo + Al + Ca + K = 0,05;
    C – 0,004-0,008; N – 0,001; H – 0,0001; O – 0,001-0,009

     

    Alloy type Bars  dimensions, mm Base element, W, % Impurities, not more (%)
    BL Diameter  – 1-10, length  ≥ 150 ≥ 98,9-99,15 La₂O₃ –  0,85-1,1; Al + Fe + Mo + Si + Ca < 0,04
    Alloy type Bars  dimensions, mm Base element, W, % Impurities, not more (%)
    ВТ-15 diameter  – 4-9, ≥ 99,94 ThO₂ – 1,5-2; other impurities total < 0,09
    ВТ-50 length  ≥ 100 ThO₂ – 4,5-5,5; other impurities total  < 0,1
    ВТ-7 diameter  1-12, length up to  1000 ≥ 99,95 ThO₂ – 0,7-1; other impurities total < 0,05
    ВТ-10 ThO₂ – 1-1,5; other impurities total  < 0,05
    ВТ-30 ≥ 99,94 ThO₂ – 2,5-3,5;other impurities total  < 0,06
    ВТ-50 ThO₂ – 4,5-5,5; other impurities total  < 0,06
