Active Metal Brazing

INTA Technologies Corporation has a proprietary process for active metal brazing of metal components directly to ceramic components. The process is done in a vacuum furnace at approximately 900 degrees C. Every application for ceramic to metal joining is analyzed to determine the most cost effective process for our customers requirements. Common materials used in successful Active Metal Brazes include zirconia or alumina to stainless steel or molybdenum. Active metal brazing is a one-step operation done at high temperatures in a vacuum or controlled atmosphere furnace. This method can be automated and performed in a batch furnace for large volume orders. The advantage of this method over ceramic metallization lies in elimination of a heat treating step and plating of the metalization. Active metal brazing can be more cost-effective than Cu-Sil brazing although the joints are typically less robust and more prone to voiding in comparison to Cu-Sil hermetic brazing. INTA can readily provide brazed assemblies that are helium leak tight to 10 to the -9 cc/sec and even tighter. Contact our sales office to discuss your project.
