Brazing Methods at Elcon
Furnace Brazing
Ideal for consistent, repeatable production, furnace brazing is one of Elcon’s core strengths, enabling the efficient joining of components with complex geometries across high-volume production runs. Our advanced, computer-controlled furnaces offer tight thermal control, ensuring precise heat application and uniform brazing temperature distribution throughout the brazing cycle. This results in strong, reliable joints with minimal thermal distortion.
Hydrogen Brazing
Utilizing a pure hydrogen atmosphere, this brazing method produces oxide-free and extremely clean joints, making it especially well-suited for medical and aerospace applications. The reducing nature of hydrogen prevents oxidation during the brazing process, enabling precise, reliable bonds between metals and ceramics using the appropriate filler metal. Elcon’s hydrogen brazing process is tightly controlled to ensure consistent joint quality and integrity.
Vacuum Brazing
Ideal for components that demand joints free of oxide contaminants and exceptionally clean surfaces, without the need for post-processing. This method is conducted in a high-vacuum environment, which eliminates oxygen and other reactive gases that could otherwise compromise the quality of the braze joint. As a result, it produces strong, high-integrity bonds with excellent metallurgical cleanliness and enhanced corrosion resistance.
Controlled Atmosphere Brazing
This method is particularly effective for applications where surface cleanliness is critical but vacuum brazing is not required. It also allows for greater throughput and is well-suited for medium- to high-volume production runs. Elcon’s controlled atmosphere brazing solutions are ideal for assemblies in energy systems, automotive components, and thermal management applications, where consistent quality and metallurgical stability are essential.

The selection of materials is a critical factor in the brazing process, as it directly impacts the strength, durability, and overall quality of the joint. Ultimately, material choices must be carefully matched to the specific application, considering factors such as operating temperature, mechanical load, and environmental exposure to ensure optimal results.
Serving the Most Critical Industries
High-quality brazing services are essential across a wide range of industries, including aerospace, medical, and automotive, where components must meet strict performance, safety, and reliability requirements. In the aerospace sector, precision brazing, silver brazing, and hydrogen brazing are commonly used to create durable, high-strength joints that can withstand extreme temperatures and stress—conditions where failure is not an option. In medical applications, particularly for implantable or diagnostic devices, ceramic-to-metal brazing provides clean, hermetic seals that ensure both patient safety and long-term device performance. Within the automotive industry, furnace brazing is critical for the production of heat exchangers, sensors, and electronic modules, where consistent quality and thermal efficiency are vital. Across all these sectors, the integrity of a brazed assembly directly impacts system functionality and longevity, making expert-level, application-specific brazing a cornerstone of advanced, high-reliability manufacturing.
