  • Furnace brazing in accordance with MIL-B-7883 Type II and other widely recognized and accepted procedures.
  • Protective atmospheres including pure dry hydrogen, argon, nitrogen, helium or vacuum to eliminate oxidation or other contaminants, and ensure optimal wetting, brightness and joint quality of the finished assemblies.
  • Brazing of stainless and carbon steels; 904L, Carpenter 20Cb-3; nickel alloys such as Monel 400, Inconel 600, and Hastelloys; lead-free brasses; OFHC copper; beryllium-copper and other base metals.
  • Active alloy vacuum brazing of tantalum, titanium, etc.
  • Metallized ceramic windows and ceramic-to-metal feed-thru assemblies may be incorporated into braze
  • Filler metals including a wide variety of gold, silver, copper, and nickel-based alloys.
  • Fluxless brazing for high-vacuum applications.

We excel at difficult and complex assemblies of OFHC copper, stainless and Monel or other components which must be assembled by step-brazing using multiple filler metals.

Certifications are available in accordance with your process and quality control specifications (subject to our review), or to widely accepted brazing procedures and specifications.
