ASTM F106-12

Standard Specification for Brazing Filler Metals for Electron Devices

ABSTRACT
This specification covers brazing filler metals for use in electron devices in a nonoxidizing atmosphere. Material covered by this specification consists of vacuum grade (Grades 1 and 2) brazing filler metals manufactured in the form of strip, wire, or preforms made by blanking the trip or bending the wire. Brazing filler metals in the form of powder are also available. Filler metals in wire form shall be in soft temper condition, most suitable for hand feeding or ring winding in mandrels, while those in strip form shall be in hard as-rolled temper condition to facilitate clean blanking of thin shims or preforms. The surface of the filler metal, whether strip, wire, or preform, shall be as smooth and free of dirt, oxide, pits, deep scratches, seams, slivers, stains, scale, blisters, edge cracks, trimming burrs, waves, wrinkles, and other defects as commercially possible. Melting test for cleanness and spatter shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers requirements or filler metals suitable for brazing internal parts and other critical areas of electron devices in a nonoxidizing atmosphere (Note 1).
1.2 These materials are available in strip or wire or preforms made by blanking the strip or bending the wire. Powders are also available.
Note 1—Brazing filler metals for general applications are specified in AWS Specification A 5.8.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
