Brazing Components for Refrigeration Today, we address correct brazing alloys as well as proper brazing methods for refrigeration components. Our main topics are: Alloy selection Gas and torch selection Brazing method Nitrogen purge System evacuation and charge Remember, brazing in the HVAC/R ...

Aluminum brazing has become prevalent in the automotive and HVAC/R industries. Most manufacturers are using all-aluminum or mostly aluminum components, including evaporator and condenser coils, distributors, liquid and suction lines. When brazing aluminum, two families of fluxes are commercially ...

Copper-Phosphorous Alloys for Copper Brazing The alloys copper-phosphorous and silver-copper-phosphorous were patented in the U.S. in 1914 and gained popularity when new refrigerants were developed to replace ammonia. These refrigerants enabled the use of copper to facilitate the increased demand ...

Aluminum-Copper HVAC Protection The HVAC/Refrigeration industry is converting many components from copper to aluminum. The reasons? Aluminum is less expensive by weight, is more corrosion resistant, weighs less, and maintains similar heat-transfer rates to copper. These aluminum parts are joined to ...

Liquid Metal Embrittlement Liquid Metal Embrittlement (LME) may occur in a brazing operation involving high-strength materials such as stainless steels, nickel alloys or age-hardened alloys, when the materials are stressed and come into contact with molten brazing filler metal. Many cases have been ...

Braze 560 alloy is a near eutectic. Watch our three-minute video to see how this material freely wets and flows on brass and copper components. We will show you the critical steps for successfully fluxing and brazing parts to achieve quality joints. Watch for tips on the correct amount of flux to ...
