Brazed Assembly Services

Ceramic-to-Metal and Metal-to-Metal Brazing

Elcon Precision provides high-reliability brazing services and precision brazed assemblies for aerospace, defense, semiconductor, industrial, medical, and energy applications. With more than 50 years of manufacturing experience, advanced furnace brazing capabilities, and comprehensive in-house support services, we produce strong, hermetic, and highly repeatable brazed joints for mission-critical environments.

From metal-to-metal joining to complex ceramic-to-metal assemblies, our controlled brazing process delivers exceptional joint integrity, dimensional stability, and long-term performance where failure is not an option. Elcon works largely with clean, low-vapor alloys and carefully selected brazing filler metal options to support prototype and high-volume manufacturing with greater quality control from start to finish.

In addition to advanced brazing capabilities, Elcon also provides in-house ceramic metallization, electro and electroless precision plating, glazing, cleaning, and fixture machining to support complex assembly requirements.

Our experienced team of engineers will select the appropriate brazing fixtures, joint design, and process best-suited to your application

Our Brazed Assembly Process

—

Depending on the material type, part geometry, thermal expansion requirements, metal surfaces, ceramic surfaces, and final operating environment, Elcon’s engineering team selects the brazing fixtures, joint design, braze alloy, and process best suited to the application.

Through atmosphere brazing, vacuum brazing, furnace brazing, and partial pressure brazing, we join metal components and ceramic components in controlled environments that help protect assemblies from oxidation. When the application calls for direct ceramic joining without metallization, active metal brazing can be a cost-effective solution performed by our in-house team.

Controlled furnace brazing is especially useful for complex geometries, ceramic-to-metal bonding, dissimilar materials, and assemblies with multiple joints because components can be heated uniformly in a protected environment.

Elcon is also capable of joining metal components by laser, TIG, and spot welding. For applications where a clean, controlled, flux-free furnace environment is required, learn more about our vacuum brazing services.

Brazed Assemblies for Extreme Operating Conditions

Elcon’s metal and ceramic brazing services support manufactured components used in extreme conditions where reliability, hermeticity, and long-term performance are critical.

Our brazing techniques are essential for producing components such as power grid tubes and vacuum interrupters, where maintaining a hermetic seal in high-vacuum environments is critical. These applications require reliable operation under high voltage and current conditions, helping prevent gas leaks while improving component longevity and performance.

Elcon’s brazed assemblies are also used in applications where thermal cycling, heat exposure, tight tolerances, complex geometries, and demanding electrical requirements make conventional joining methods difficult to use reliably.
