Abstract
A wire (10) for use in a brazing or soldering operation has an elongated body (12) of a metallic material. The elongated body (12) has an outer surface (18). A channel (14) is formed along a length of the body. The channel (14) has an opening (A1). A flux solution (22) is deposited within the channel (14) and along the length of the body. The flux solution (22) covers a portion of the outer surface (18). A portion of the flux solution (22) is exposed through the opening (A1) in the channel (14).
Claims14
A wire for use in a brazing or soldering operation, the wire comprising:
- an elongated body of a metallic material;
- a channel having an opening formed along a length of the elongated body, the opening having a width of about 30% to 70% of a major axis of a cross-section of the elongated body;
- a cured flux solution formed by curing a flux solution comprising a polymer-based binder material and a flux material within the channel and along at least a portion of the length of the elongated body with a surface of the cured flux solution being exposed through the opening in the channel wherein the wire is formed into an annular ring and wherein the cured flux solution within the channel forms a portion of an inner wall of the annular ring.
