4104/3003/4104 aluminum plate sheets for Oil cooler board

The heat for brazing is typically provided by a hand-held torch, a furnace or an induction heating system. Other techniques include dip brazing and resistance brazing.

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.

Furnace brazing does not required a skilled operator, and is often used to braze many assemblies at once. This method is only practical if the filler metal can be pre-positioned.  Furnaces normally must be left on 24/7 to eliminate long start up and cool down delays, and are not particularly energy-efficient.

Dip brazing is used for small wires, sheets and other components that are small enough to be immersed. The parts are dipped in a molten flux bath which doubles as the heating  agent. Resistance brazing is effective for joining relatively small, highly conductive metal parts. Heat is produced by the resistance of the parts to the current.
*Various specifications for fin and plate
*Perfect  strength after brazing
