At what temperature do most brazing fillers begin to melt?

The melting point of most brazing fillers typically ranges from approximately 1100°F to 1200°F. Therefore, the choice that states 1100°F is the most accurate, as it aligns with the standard melting temperatures for common brazing alloys.

Brazing is a process where the filler metal is heated above its melting point, allowing it to flow into the joint and create a strong bond between two base metals. When selecting a filler, it’s essential to know its melting temperature to ensure that the base metals do not reach their melting points, which could compromise the integrity of the joint.

The other temperatures listed do not commonly correspond to the melting points of most brazing materials, which typically require higher temperatures than those suggested by the alternative choices. Understanding these temperature ranges is crucial for effective brazing practice, as using a filler that melts at an inadequate temperature could lead to insufficient bonding and joint failure.
