AM Au-3 Wire 35% Au / 62% Cu / 3% Ni - NICORO 35% Gold 62% Copper 3% Nickel Wire

Uses

AM Au-3 Gold Brazing Alloy is used on most ferrous and non-ferrous alloys, and provides an excellent hermetic braze to Nickel, Kovar, Stainless Steel, and Molybdenum. AM Au-3 primary applications include brazing of electron tubes, vacuum tubes, and wave guides in the electronic industry. Uses also include hermetic seals, metallized ceramics, ceramic to metal seals, glass to metal seals, and step-brazing applications.  AM Au-3 has minimal diffusion and is an ideal alloy for nickel plated components. 

Brazing Characteristics

AM Au-3 Gold Brazing Alloy can be successfully brazed onto a wide range of high temperature applications like microwaves, satellites, wave guides, klystron tubes, medical equipment, solid state power amplifiers, pressure windows, power transmitters, and laser assemblies. AM Au-3 offers better strength characteristics then other Au/Cu braze alloys with higher ductility. A minimum brazing temperature of 1890°F (1010°C) is recommend for furnace and vacuum applications. AM-Au-3 is not recommended without a protective cover or shielding gas and it is recommended that the shielding gas be under partial pressure (Argon or Nitrogen) due to the high vapor pressure of copper within the alloy.
