  • Publication number: 20110011920
    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.

  • Patent number: 5706979
    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.

  • Patent number: 5556562
    Abstract: An improved welding assembly for metal inert gas welding wherein the welding assembly includes a continuous filler metal wire electrode, which is electrically charged and passed through a contact tip generally of a cylindrical shape with a central aperture or tunnel therethrough while the work piece is oppositely charged. The improvement is in the composition of the contact tip in that the tip is made of copper and carbon.

  • Patent number: 5066456
    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.
