What is the required melting point for brazing alloy?

The melting point for brazing alloys is required to be above 1000°F. This is significant because brazing involves the use of a filler metal that melts and flows into the joint between two base metals. A melting point above 1000°F ensures that the filler metal can adequately penetrate and bond to the base metals without the base metals themselves melting, which would compromise the integrity of the joint. In brazing processes, the goal is to create strong, durable connections at high temperatures without damaging the substrates being bonded. This temperature threshold helps in effectively achieving the desired mechanical properties and strength of the joint in various applications, particularly in medical gas line fittings where reliability and safety are critical.
