At what temperatures is most brazing performed?

Most brazing is performed at temperatures above 1200 Fahrenheit. This is because brazing involves melting a filler metal that typically has a melting point higher than that of soldering but lower than that of welding. The filler metals used in brazing generally require temperatures in this range to properly flow into the joint and create a strong bond between the base materials.

Achieving these elevated temperatures allows for better penetration of the filler metal into the joint, which is essential for the formation of a durable connection. This high-temperature process also facilitates the diffusion and bonding of the base metals and filler, resulting in improved mechanical properties in the finished joint.

Additionally, using these higher temperatures can reduce the risk of contaminating the joint area with oxides, which can weaken the bond. As a result, brazing is often chosen for applications requiring high strength and resistance to thermal stresses, and the typical process temperature range aligns with those requirements.
