A non-crevice corroding clip-to-strand braze joint using a braze alloy that is essentially free of phosphorous, one of the key factors of the known crevice corrosion mechanism, is provided to improve generator availability and reliability, and a method for forming the same is provided. In a brazed joint between an armature bar strand package and an end fitting(16), the brazed joint comprises: pluralities of solid strands(18) and hollow strands(20) that are arranged in a layered array and form the strand package, wherein the plurality of hollow strands have free ends that axially extend beyond corresponding free ends of the solid strands; a cavity(28) in the end fitting, wherein the free ends of the plurality of hollow strands and the corresponding free ends of the solid strands extend through an opening and are received in the cavity; and an essentially non-phosphorous contained copper-silver braze alloy(26) for joining the free ends of the plurality of hollow strands and the corresponding free ends of the plurality of solid strands to each other and to inner surfaces(24) of the end fitting.
