The best clearance between the two metal parts being brazed is a close one - usually .001 inch to .003 inch, and generally not more than .005 inch. If the clearance is smaller than .001 inch, there ...

Brazing joins parts by heating them to more than 840°F and applying a filler metal that has a melting temperature below that of the base metal. Filler metal flows into the joint by capillary ...

A notable trend in HVAC and refrigeration is that contractors are increasingly repairing faulty aluminum coils and return bends rather than ordering new parts. Two factors are driving this change: ...

Brazing is the process of combining two metals using a filler material that melts, flows, and wets the surfaces of the metals at a temperature lower than the melting point of the metals. A covering ...

New research shows small additions of nickel and yttrium can dramatically improve the performance of aluminum brazing fillers. This could be a route to stronger joints at lower processing temperatures ...
