Product Description

Aluminum Radiator 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.
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.

 
*Various specifications for fin and plate 
 
*Good mechanical property and surface condition 
 
*Excellent collapse resistance during brazing 
 
*Perfect strength after brazing
