GoldAlloy BV-ACS-75
Nominal Chemical
Composition
INTRODUCTION
Aufhauser GoldAlloy BV-ACS-75 is a special alloy for vacuum brazing.
APPLICATIONS
GoldAlloy BV-ACS-75 is used on any ferrous and non-ferrous alloys. It has excellent vacuum properties along with high corrosion and oxidation resistance. It is a more ductile than standard gold-copper alloys. GoldAlloy BV-ACS-75 is used in vacuum, inert or reducing atmosphere.
