Product Description

Aluminum Engineering Machinery 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.

Because brazed joints have a very clean, well-finished appearance, brazing often is the preferred bonding process for manufacturing plumbing fixtures, tools, heavy construction equipment and high-quality consumer products.
 
*Perfect surface condition and tolerance control 
 
*Good consistency for any fin mill
 
*Excellent collapse resistance and strength after brazing
