Brazing Alloys

Besides solder alloys, Array Solders also offers materials for brazing applications. Brazing is essentially a high-temperature form of soldering that, when properly done, provides extremely strong, leak-tight, corrosion resistant joints. Most of the common (and easy to use) brazing alloys contain silver and the amount of silver in the alloy can affect how that material melts and flows. When brazing (and soldering), the metals being joined are not melted, but a filler metal is used to bond the materials being joined. A separate flux is sometimes necessary to help maintain a clean, oxide-free joint surface.
