Tungsten alloy member, and using the discharge lamp tungsten alloy member, and a magnetron transmitting tube

Object of the present invention is to obtain a non-radioactive material is used as a thorium-tungsten alloy also has the same or higher than thoriated tungsten alloy emission characteristics, and to provide the use of a tungsten alloy discharge lamp, and a magnetron transmitting tube tube. Tungsten alloy of the present invention, contains ZrC terms of Zr component in the range of more than 0.1wt% 5wt% or less.
