X-ray anode having improved heat removal

An X-ray anode for generating X-rays, the X-ray anode comprising:

• a support body;
• and
• a coating joined to said support body for generating the X-rays upon bombardment with focused electrons;
• said support body having a strength-imparting region composed of a material with a strength of greater than 100 MPa at 500° C., said strength-imparting region being formed of 0.5% by weight of Mo, 0.08% by weight of Ti, 0.01 to 0.06% by weight of Zr, 1.2% by weight of C or Mo, 0.04 to 0.15% by weight of Hf and C;
• and
• said support body having a region composed of a diamond-metal composite containing from 40 to 90% by volume of diamond grains.
