Copper-phosphorus brazing alloys are used to connect copper to copper in HVAC/R applications, as well as in industries that use electrical conductors.
Copper, silver brazing without flux, which is suitable for air conditioning, refrigerator, evaporator, heat exchanger, water heaters, and other copper alloy brazing.
Brazing, or braze welding, is a metal-joining process. During this process, a filler metal is heated above the melting point, then distributed by capillary action between two or more close-fitting parts. It can braze a joint or fill a hole.
Brazing wire is a common brazing filler metal.
