Product Description

Aluminum /Aluminium Air Cooling Fin for Tubes (1060/1100)

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.

Method of brazing:
The step by step procedure for brazing is as follows:
1.The metal parts which are to be brazed must be thoroughly cleaned.
2.The flux must be applied to the surface. 
3.The parts are to be clamped in the required position.
4. The flux ha to be applied on the surfaces. 
5.The job has to be heated using the blow torch or the furnace etc.
6. The molten spelter has to be allowed to flow by capillary action into the joint. 
7.The job has to be allowed to cool slowly.

*Good consistency for any fin mill
 
*Good mechanical property and surface condition
