Copper-ABA Foil Active Braze Copper Foil2.25% Titanium Braze Alloy

Copper-ABA Brazing Alloy is a high purity active braze alloy. Copper-ABA is alloyed - Copper, Silicon, Titanium, and Aluminum. Copper-ABA is primarily used to braze directly to ceramic surfaces without metallization. This includes all ceramics and ceramic composites and virtually all ferrous and non-ferrous metal surfaces including carbides and diamond. Copper-ABA allows for ceramic-to metal and ceramic-to-ceramic surfaces to be brazed without metalizing, firing, and electroplating producing vacuum-grade hermetically sealed assemblies.  92.75% Copper 3% Silicon 2.25% Titanium 2% Aluminum
