Active Brazing Alloys

Active Brazing Alloys eliminate the need for traditional ceramic metallization prior to brazing as the active components promotes wetting on the ceramic surface.

active brazing alloy materials

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, preforms, wire and paste.
