Rotary anodes for X-ray tubes are provided having improved thermal stability. The rotary anodes are comprised of a basic body made of molybdenum alloy comprising about 0.1 to 15% by weight hafnium, about 0.1 to 15% by weight zirconium, about 0.01 to 1.0% by weight carbon and the balance molybdenum. The alloy according to the invention has a low tendency of cracking distortion, and/or surface roughening, even with focal track zones made of tungsten and tungsten alloys and even at operating temperatures exceeding the currently normal values by up to about 200 DEG C.
