ABSTRACT:
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.
