Aluminum Oil cooler fin and board

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.

Brazing is relatively fast and economical, requires relatively low temperatures and is highly adaptable to automation and lean manufacturing initiatives.

*Various specifications for fin and plate 

*Perfect strength after brazing
