Claim:
1. A wire for use in a brazing or soldering operation, the wire comprising: a ring formed from a metallic material, the ring having a first end and a second end and is centered about a longitudinal axis; a pair of channels extending along an inner circumference of the ring perpendicular to an axis of the ring, each channel having an opening formed along the circumference of the ring facing the longitudinal axis of the ring; a divider formed by a portion of the ring separating the pair of channels, the divider having opposing planar walls extending outwardly from corresponding planar base portions of the pair of channels wherein each of the base portions are co-planar, the opposing planar walls terminating at distal ends wherein a first engagement surface is formed therebetween; a pair of outer planar walls separated by the pair of channels and the divider, the outer walls each extending outwardly from the corresponding base portions of each of the pair of channels; a second engagement surface formed between an outer surface of the ring and a terminal end of one of the outer walls; a third engagement surface formed between the outer surface of the ring and a terminal end of the other of the outer walls and substantially coplanar with the second engagement surface; and a cured flux solution within the pair of channels, wherein corresponding surfaces of the cured flux solution are exposed through the opening in each channel.
