Brazing Alloys for Photo Etched Preforms
Photo etching brazing alloy preforms saves time, cost and reduces scrap. Photo etching avoids many problems associated with stamping, die-cutting, laser, or digital knife plotter-cutting of these expensive alloys.
Popular Brazing Alloys that can be Photo Etched
Many popular alloys are suitable for etching, including:
Aluminum: AMS 4047, 4184, 4185
Nickel: AMS 4776, 4777, 4778, 4779, 4782
AWS: BNi5A, BNi5b, BNi6, BNi9
Copper: AWS BCu-1, BCu-1a, BCu-2, BCu-3, BCu-1b
Silver: AMS 4767, BVAg-0
Other alloys may also work, but would require testing to confirm.
