 Active Brazing Alloys
(ABA)®
Active Braze Alloys eliminate the need for traditional ceramic metallization
prior to brazing as the active components promotes wetting on the ceramic
surface. One-step brazing with ABA® replaces metallizing, firing and
electroplating, offering savings in time and cost. ABA®’s are
available in Gold, Silver, Titanium and Copper based materials and offer
highly reliable hermetic seal between ceramic and metal for both oxide
and non-oxide ceramics. Available alloy forms include foil, wire and paste.
