Product Description

Aluminum strip coil for tubes

Brazing is a metal joining process utilizing a filler metal that melts above 840ºF and below the melting point of the base metals. The filler metal is drawn into the joint by capillary attraction producing a sound, leak-proof connection.

Each of these flow at specific temperatures and are available as wire, foil, paste, powders, and preforms. Filler metals typically have significantly different compositions from the materials being joined, for this reason their selection is critical to successful brazing.
