A phosphorus-copper based brazing alloy comprising by weight: 6.0% to 7.0% phosphorus; about 2% to about 8% tin; about 2% antimony; and the balance copper. A process of using this alloy to produce a brazed joint with a raised shoulder and with little black oxide.
A solid phos-copper base brazing alloy component for forming a brazed joint with a raised shoulder and little to no black oxide. The brazing alloys of the present invention are visually distinguishable from copper and copper alloy parts and may provide a good color match for silver and silver alloys, including sterling silver. The solid brazing components of the present invention may be used in forming brazed joints at low brazing temperatures and result in a joint that is ductile, smooth and corrosion resistant. The solid brazing components are provided in the form of wire, strip, foil or a preform, and thus are advantageously used in a wide variety of brazing applications including copper tubing and intricate jewelry. The brazing components of the present invention are made of an alloy having a liquidus temperature above 840 F. and consist essentially of about 4-10% phosphorus, about 0.1-8% tin, up to about 4% antimony, about 0.001-3% silicon, up to about 18% silver, up to about 3% nickel, up to about 3% manganese, with the balance being copper. Exemplary embodiments include about 0.1-18% silver and/or 0.1-3% nickel.
A phosphorus-copper based brazing alloy comprising by weight: 4.0% to 8.0% phosphorus; about 0.1% to about 8% tin; 0% to about 2% antimony; and the balance copper. A process of using this alloy to produce a brazed joint with a raised shoulder and with little black oxide.
A solid phos-copper base or silver-phos-copper base brazing alloy component for forming a brazed joint with a raised shoulder, little to no black oxide, and improved corrosion resistance. The brazing alloys of the present invention are visually distinguishable from copper and copper alloy parts. The solid brazing components of the present invention may be used in forming brazed joints at low brazing temperatures and result in a joint that is strong, ductile, smooth and corrosion resistant. The solid brazing components are provided in the form of wire, strip, foil or preform, and thus are advantageously used in a wide variety of brazing applications including copper tubing. The brazing components of the present invention are made of an alloy having a liquidus temperature above 840 F. and consist essentially of about 4-9% phosphorus, about 0.1-10% tin, up to about 4% antimony, about 0.1-15% nickel, up to about 3% silicon, up to about 18% silver, up to about 3% manganese, with the balance being copper. Exemplary embodiments include about 6-15% silver and/or 5-8% nickel.

Exemplary embodiments include about 6-15% silver and/or 5-8% nickel.
A method of forming a brazed joint is provided in which a surface portion of a first metal part is placed in contact with a surface portion of a second metal part to form a contact area therebetween, and the first and second metal parts include copper, silver and/or gold as the primary base metal(s) and at least the surface portion of the first metal part is a modified alloy of the primary base metal(s) having 0.5-12 wt. % phosphorus as a modifier. The surface portion of the first metal part is heated to a temperature sufficient to cause the phosphorus to wet the surface portion of the second metal part and to flow a low melting portion of the first metal part into the contact area by capillary attraction to form the brazed joint between the first and second metal parts.
A brazing alloy is provided in the form of a wire, rod or preform, and is made of, in weight percent: 3-7.5% P, 0.1-1.9% Zn, 0-74.7% Ag, 0-80% Au, 0-10% Sn, 0-5% Ni, 0-3% each of Si, Mn, Li, and Ge, and the balance copper in an amount of at least 21.7%. In additional embodiments, Zn may be present in an amount of 0.6-1.9%. A method of torch brazing is also provided. The method includes forming the alloy into a wire or rod, placing the tip of the wire or rod in contact with a surface of a joint, heating the joint surface using a torch flame, and contacting the tip of the wire or rod to the heated joint surface to melt and flow the alloy onto the joint surface and into the joint under capillary action.

C22C 902
US Classification:
420472
Abstract:
A phosphorous copper based alloy having combined tin and antimony contents up to approximately six percent each for brazing filler metal joining copper and copper alloys producing strong clean joints at lower brazing temperatures. Silver added in amounts of 1-18% offers the ability to lower brazing temperatures further.
