Product Description

Aluminum Parallel Condenser fin

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.
Torch brazing is often used for small assemblies and low-volume applications. A "neutral" flame with a bluish to orange tip, a well-defined bluish white inner cone and no acetylene feather works the best; a flame with a colorless tip can cause oxidation. Although the quality of the joint is largely dependent on operator skill and consistency is sometimes an issue, torch brazing requires only a small investment and is very popular.

*Various kinds of specification for fin
 
*Excellent collapse resistance during brazing
