1. An x-ray tube comprising:
an x-ray tube envelope comprising an interior;
an anode assembly disposed within the interior of the x-ray tube envelope; and
a cathode assembly disposed within the interior of the x-ray tube envelope that emits an electron beam to strike a target surface of the anode assembly and form electromagnetic radiation,
wherein said x-ray tube comprises a braze assembly, said braze assembly comprising a first component and a second component joined together by a first braze joint, said first braze joint comprising a composition configured to comprise a solidification temperature range of no more than 90° C. and a liquidus temperature in the range of 950° C. to 1060° C.; said braze joint comprising no more than 18.0 wt % in total of one of more precious metals selected from Au, Pd and Pt, relative to the total weight of the first braze joint, wherein at least a portion of the braze joint is exposed to the interior of the x-ray tube envelope and wherein at least one of the first and second component form part of one or more of the x-ray tube envelope, the anode assembly and the cathode assembly.
