A rotating anode target for X-ray devices comprises a circular graphite disc structure both of whose front and back sides or faces taper equally towards each other and define a narrow rim surface and central hub section. A larger area of the front face is coated with a focal track metal which extends coextensively over the front face to overlap part of the rim surface. The slant height dimension of the focal track metal is greater than the diameter of the hub section.

X-ray tube anode target

An improved rotary x-ray target wherein a rotor stud member is fastened to a hub portion, with both the stud member and the hub portion composed of a refractory metal. The fastening of the stud member to the hub portion is effected by a brazing alloy composed of the following ranges of metals expressed in weight percent: 30-70 copper; 10-55 palladium and 5-28 nickel. The brazed joint has a liquidus temperature in the range of 1145.degree.-1200.degree. C. and thus allows operating temperatures for the stud/hub joint of at least as high as 1000.degree. C.
