Braze Alloys
Incusil®-ABA® Technical Information
High-purity Active Braze Alloy of silver, copper, indium and titanium developed for direct application to ceramic surfaces
Key Benefits
- Wets and bonds to virtually any metallic surface, as well as to non-metallics such as oxides, nitrides and carbides
- Allows ceramic-to-ceramic and ceramic-to-metal surfaces to be brazed without metallizing, firing and electroplating
- Cuts time and costs in manufacture of ceramic/metal assemblies
- Produces strong, highly reliable and vacuum-tight brazed joints
Typical Applications
- One step bonding to ceramics
Nominal Composition by Weight
- Silver (Ag): 59.0%
- Copper (Cu): 27.25%
- Indium (In): 12.5%
- Titanium (Ti): 1.25%
Suggested Base Materials
Copper, Kovar, Nickel, Carbon/ low alloy & Tool/high speed steel, Stainless steel, Ni-super alloys, Titanium, Refractory metals, Ceramics, Graphite, Diamond, Tungsten Carbide
