This detailed article explores brazed assemblies in critical aerospace parts—including thermocouple sensors, sapphire viewports, RF power cavities, and pitot probes. It discusses how vacuum brazing enables hermetic sealing, joining dissimilar materials, and ensuring consistent quality under extreme operating conditions, making it ideal for safety‑critical aviation applications.
The components shown above are H13 tool steel and tungsten carbide assemblies processed in a Normantherm vacuum brazing furnace. This material combination is commonly used in punching tools, wear parts, forming dies, and cutting applications where both toughness and wear resistance are required.
