Brazing Filler Metal Melting Point

The filler metal must have a melting point above 450°C (840°F).

Advantage of Brazing

Brazing can effectively join different types of metals together.

Brazed Joints Strength

Brazed joints usually have less strength compared to welded joints.

Color of Brazed Joint

The color of the filler metal in the brazed joint may not match the color of the base metal parts.

Capillary Action in Brazing

For brazing to work, the filler metal needs to wet the base metal surfaces through capillary action.
