Of all the methods available for metal joining, brazing may be the most versatile. Brazed joints have great tensile strength - they are often stronger than the two metals being bonded together. Brazed joints repel gas and liquid, withstand vibration and shock and are unaffected by normal changes in temperature. Because the metals being joined are not themselves melted, they are not warped or otherwise distorted and retain their original metallurgical characteristics.

*Various kinds of specification for fin

*Excellent collapse resistance during brazing

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.

*Perfect brazing feature, fit for any furnace    

*Good consistency for any fin mill

*Excellent collapse resistance during brazing
