  • Back to the future with copper brazing
    alloys don't lose strength after brazing. * Brazing pastes and foils alloy with base metals to form joints. * 650 C brazing in nitrogen forms strong, reliable heat-exchanger cores. , has a CuproBrazing Handbook, video explanation, and supplier listing. "A cooling core of copper-brass could finally
  • Improvement in Joint Quality and Reduction of Flux Usage with Ag Based Handy One (R) Products (.pdf)
    Lucas Milhaupt Handy One brazing alloys and materials can improve braze joint quality and reduce flux usage. Handy One (R) flux cored brazing alloys have been introduced to the brazing industry in order to limit the inconsistencies seen with traditional application of brazing fluxes and solid alloy
  • Corrosion-Resistant Braze Joints (.pdf)
    examinations of all. the filler metals were performed. on solid buttons prepared by melt-. ing the powder in a ceramic cru-. cible in a vacuum furnace. Optical. micrographs revealed 3 distinct. phases in each of the alloys: a ma-. trix phase, a primary precipitated. phase, and a eutectic-like struc-. ture
  • Paste or Preforms, the Brazer's Question (.pdf)
    There is a spirited debate among manufacturers involved in copper brazing in controlled atmosphere furnaces. Which form of filler metal is better to use; paste or preforms?. Furnace brazing differs from hand brazing and many types of open air brazing in that the filler metal must be pre-placed
  • Solving the Problems Inherent to Torch Brazing Aluminum (.pdf)
    products challenges. manufacturers to rethink their brazing techniques, filler metals, and fluxes. BY KENNETH ALLEN. The volatility in the price of copper. has removed cost certainty for man-. ufacturers of copper heat-transfer. devices. This market instability and the es-. calating warranty claims
  • Seven Steps to Successful Brazing
    oxide formation during heating. Wolverine's line of brazing fluxes, including Ultra Flux and Black Flux, are engineered to provide optimal protection. When joining copper to copper using one of the Silvaloy B-CuP alloys, an external flux is usually not necessary as the phosphorous in the alloy acts
  • Brazing Processes
    not oxidize at the brazing temperature or can be protected from oxidation with a flux. The most commonly used filler metals include aluminum-silicon alloys, silver-base alloys, and copper-zinc alloys. Flux is required with these filler metals unless protective atmosphere is used. Self-fluxing
  • The Friction Welding Advantage
    variety of materials that can't be combined using conventional welding techniques can be bonded using friction welding. Friction welding can join two dissimilar materials in a full-strength weld without sacrificing weld integrity or strength. Alloys, medium-carbon and high-carbon steels can, in many cases
  • Medical Device Link .
    melting point (below the melting point of the base metals) is added to the joint and reflowed in place. Among such materials are tin-lead, gold-tin, and copper-silver alloys. Common reflow methods include rapid infrared heating using quartz lamps or parallel-resistance seam welding set up to reflow
  • Welding Techniques for Joining Sensor Bodies
    the importance of minimal heating and consistent control of weld penetration. Occasionally, a design calls for materials that are difficult to weld, such as Hastelloy, beryllium, brass, or aluminum. Heat-treatable alloys require special consideration in the development of weld parameters so
