Abstract:
It is an object to provide a tungsten alloy exhibiting characteristics equal to or higher in characteristics than those of a thorium-containing tungsten alloy, without using thorium which is a radioactive material, and a discharge lamp, a transmitting tube, and a magnetron using the tungsten alloy. According to the present invention, a tungsten alloy includes 0.1 to 5 wt % of Zr in terms of ZrC.
