Question:

What is the difference between A and B grade brazing alloys?

Answer:


Grade A,has rigid tolerances of ribbon width and thickness. Grade B has larger variations in these parameters. Both grades have the same composition and the composition variations relative to the nominal composition.
  1. What is Metglas?
  2. Can Metglas Brazing Foil be used to join steel plates?
  3. Where is Metglas manufactured?
  4. What are the sizes and shapes of the Metglas products?
  5. Is the Metglas product available in rod, plate or bar form?
  6. Does Metglas Produce a Brazing Powder?
  7. If I use Metglas Brazing Foil in my EGR Cooler design, what kind of design advantages can I expect?
  8. If I switch from using brazing powder to Metglas Brazing Foil for joining steel plates and fins in my automotive heat exchanger design, can I expect to have better joint strength?
  9. I am brazing stainless steel using Nickel-based brazing paste in my current automotive design and am experiencing furnace life longevity concerns - should I expect better furnace life if I use Metglas Brazing Foils instead?
  10. We have a very intricate engine design that requires metal joining and during my production cycle, we are over-spraying (and subsequently wasting) a lot of brazing powder. Is there a way to reduce the amount of waste I am experiencing with my brazing materials?
  11. What of is the best amorphous material for shielding a large magnetic field?
  12. What is the best alloy for flux gate magnetometers?
  13. Do you provide security sytems to prevent theft?
  14. Where can I find bobbins for POWERLITE cores larger than AMCC-100?
  15. How is 2826MB sold?
  16. Can I get a micrographs of metallic glasses?
  17. What is the best material for making a wind powered generator?
  18. Do you have a brazing foil with a low melting point of 100 deg c?
  19. What are all the mechanical properties of Metglas2605SA1?
  20. Which Metglas product alloy has the highest permeability?
  21. What sort of annealing (transverse, longitudinal, zero field, etc...) do you recommend for low field, DC shielding applications?
  22. How manageable is your material after annealing. I plan to wrap annealed foil around a cylindrical form to get my cylindrical shield - will the tape be able to tolerate this?
  23. Can you please explain pack factor?
  24. I would like to know more about anisotropy of METGLAS 2605SA1, does it occur at all, and if it does, how does it effect core losses?
  25. What is the permeability of 2714A?
  26. What is the thermal conductivity of METGLAS2605SA1?
  27. What is the difference between A and B grade brazing alloys?
  28. Why should I buy Metglas vs. Ferite Cores?
  29. How many years have Metglas products been provided commercially?
  30. Normally I would degauss shields with an AC current loop whose magnitude is gradually brought to zero. Does Metglas alloy respond to degaussing in the same way that Mu-metal does?
  31. For shielding purposes, how does Metglas 2714A alloy compare to Mumetal?
  32. What is the thermal conductivity of your alloys
  33. What are the advantages of using Metglas Brazing Foils material in an automotive metal substrate versus brazing powders?
  34. Do you supply bobbins for your cut cores?
  35. How long does it take to produce custom parts?
