GoldAlloy BV-ACN-81


INTRODUCTION

Aufhauser GoldAlloy BV-ACN-81 is a special alloy for vacuum brazing.

APPLICATIONS

GoldAlloy BV-ACN-81 is a high-purity gold-copper-nickel brazing alloy for vacuum brazing, remaining ductile after application. Widely used for brazing ceramic components that have been molybdenum-manganese metallized. Provides high-integrity brazed joint duties in aero-engines, aerospace fuel-line assemblies, vacuum tubes, automotive components.
