SilverAlloy A-63Ti-Active
Nominal Chemical
Composition
INTRODUCTION
Aufhauser SilverAlloy A-63Ti-Active is an active, brazing alloy that promotes wetting and good capillary action on several surfaces that would otherwise be difficult to join by brazing. It wets and bonds to nearly all metallic and non-metallic surfaces (such as oxide, nitride, carbide) and produces strong joints, dependent upon adequate treatment of ceramic seal faces.
APPLICATIONS
Aufhauser SilverAlloy A-63Ti offers highly reliable bonding between ceramic and metal for both oxide and non-oxide ceramics.
