At VT Vacuum Heat Treaters, vacuum brazing is one of our flagship specialties. Backed by decades of combined metallurgical and metal joining expertise, we deliver ultra-clean, leak-tight joints for critical engineering components without using any flux. By brazing in high-vacuum levels down to 5 x 10⁻⁵ mBar and controlled temperatures up to 1200°C, we eliminate oxidation and contamination completely.

​

Whether your components require copper, silver, nickel, or aluminum brazing, our facility routinely achieves exceptional bond strength and precision. We have proven, leak-tested experience joining complex and dissimilar materials—including Copper to Stainless Steel, Stainless Steel to Tungsten Carbide, Kovar to Ceramic, Stainless Steel to Inconel, and Aluminum to Aluminum. Every batch is processed in AMS 2750E and ISO 9001 certified furnaces, ensuring your high-value assemblies meet the toughest aerospace, defense, space, and medical quality standards.
