Solder vs. Braze

Solder and Braze

Soldering is a process in which the base metal doesn’t melt, rather, the solder itself melts to help form the attachment.

Brazing is a similar attachment technique in which the base metal also stays solid. Although braze and solder terminology is often used interchangeably, the primary difference between the two is that soldering takes place at lower temperatures and brazing takes place at higher temperatures (could be upwards of several hundred degrees Fahrenheit higher).

Your application / operating environment of your device will determine whether solder or braze is most compatible. Learn more about our custom solder and braze preforms here.
