When it comes to electrical contacts, there are several popular methods of fusion. Most people are familiar with soldering, fusion welding, and adhesive bonding. While these are often the appropriate methods to use, brazing is an often-overlooked option.
Brazing is the process of fusing two metals at a much higher temperature than is ordinarily used. Specifically, the metals being joined together are heated at over 100 degrees above the typical temperature welding temperature. In some cases, brazing is an ideal choice for electrical contacts.
