The brazing components of the present invention are made of an alloy having a liquidus temperature above 840° F. and contain of about 4-7% phosphorus, about 2-8% tin, about 2% antimony, up to about 3% nickel, 0.1 to about 3% silicon, up to about 3% manganese, with the balance being copper.

Abstract: A consumable metal joining component having identification for improved recycling has an elongated element formed from a filler metal alloy with a predetermined alloying characteristic. The elongated element has a pair of end portions and an intermediate portion extending therebetween. Each of the end portions has a compositional indicium indicative of the predetermined alloying characteristic. One of the pair of end portions and the intermediate portion of the elongated element are configured to be consumed by heat in a metal joining process. As such, the other of the pair of end portions with the respective compositional indicium remains intact to enable recycling of the remaining end portion regardless of which end portion is consumed.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A flexible cap adapted to enclose a tube having an open end and used for storing items consists of an enclosure having an opening at one end, a closed end, and side walls and enclosing a space. A pair of aligned apertures through the side walls form with the space a bore through the enclosure transverse to the axis of the enclosure between the opening and the closed end. The opening is adapted to engage the open end of the tube. To dispense an item, the cap is bent by lateral flexion so as to align one of the apertures with the open end of the tube and the tube is inverted so that an item falls out under the influence of gravity. The amount of lateral flexion controls the alignment of the aperture with the open end so as to permit only one item at a time to fall out.

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.
