Brazing - Nadcap Accredited
Brazing is a joining process whereby a non-ferrous (containing no iron) filler metal or alloy is heated to melting temperature (above 450°C; 842°F) and distributed between two or more close-fitting parts by capillary action. During brazing the molten filler metal and flux interact with the base metal, cooling to form an exceptionally strong, sealed joint. High-strength brazing can be done by annealing the braze, allowing the joint's grain structure and alloying to be controlled.
Brazing is superior to welding because it can be performed under lower temperatures, so brazing is less likely to distort the work piece or induce thermal stresses. The lower temperature of brazing also increases joining speed and reduces fuel gas consumption. Brazing can also be performed in industrial furnaces, allowing brazing to be accomplished without the use of flux. This type of brazing produces braze joints that do not require post braze cleaning.
We can perform brazing with many different filler alloys, including gold, silver, copper, and nickel brazing alloys. Our brazing services can be performed in both vacuum furnaces and inert atmosphere furnaces. All of our brazing can be performed to aerospace, medical, and military specifications and is optimized for use in these fine industries. All of our heat treating and brazing services are NADCAP accredited.
