  • Feature
  • Detail
  • Asia General can supply various aluminum brazing metal listed in national standard, and can also provide all kind of powder size according to customer’s demand. At the same time, we also provide corresponding brazing paste to each brazing alloy.

    Asia General is the first company in china to prepare low oxygen content (<300ppm) spherical aluminum powder by adopting a special powder manufacture technology. The powder can be used directly by mixed with aluminum brazing flux, and also can be formulated into paste.

    Aluminum -based paste is developed by a special process, consisting of aluminum-based brazing powder, active components, solvents, polymer carriers and other additives. The paste is exquisite. A special carrier was adopted to ensure the paste not dry with long time open storage. In addition, the paste has better brazing property for small surface area of spherical powder.
