Rings,
Strips, Shims, Washers, Discs, Edgewound, Cut-offs,
Custom Shapes are available with the following alloys
for your specific applications.
For
applications where carbide is brazed to steel, it
is often desirable to use a multi-layer brazing
alloy with a copper center, Aufhauser LayerMet.
The copper serves as an absorber of thermal expansion
as well as shock. Some of Aufhauser SilverAlloys
are available as strip and stamped preforms.
Aufhauser LayerMet (a silver-copper-silver “sandwich”)
should be used to braze large carbides to steels
or stainless steels. ( By “large” we mean bigger
than 0.5 sq. inches or 12.7mm2.) When brazing with LayerMet, the silver
on each side of the sandwich bonds with the Carbide
and the Steel. The the copper in the middle (which
melts at a higher temperature), acts to relieve
the stresses caused by unequal rates of thermal
expansion of the joined metals.
