Stay Brite(R) 8 Lead-free Silver Solder Both Stay Brite(R) and Stay Brite(R) 8 produce an overall component with greater strength than a brazed component whose base metals are weakened by annealment from high brazing heat. Stay Brite(R) solders bond with all of the ferrous and nonferrous alloys. Joints soldered with Stay Brite(R) solders exhibit considerably higher than necessary elongation for sound, dissimilar metal joints and vibration applications.
